Aantal bijdragen tijdens technical meeting: 41 (3 uit NL) Overall indruk: Beperkte discussie Oorzaak: Veel vragen van de special reporters waren gericht

aan de auteurs. Antwoorden auteurs deels interessant

Onderwerpen die tot discussie hebben geleid: NL paper A107 Root Cause Analysis of 450 MVA generator stator core fault Discussie over het tijdig kunnen achterhalen, invloed overgang base load naar start-stop bedrijf, designmaatregelen Discussie over bruikbaarheid Elcid meting - Meer ervaringen dat Elcid meting een grote bliksluiting niet vindt - Bevestiging van experts dat Elcid meting niet geschikt is voor het

vinden van fouten dieper in de kern

SC A1 – Technical meeting

Onderwerpen die tot discussie hebben geleid: Paper A105 Ensuring High quality insulation system of large motors – Design & testing requirements Discussie over kwaliteit statorwikkelingen grotere motoren en meerpolige generatoren: - Wikkelkopontladingen, te kleine afstanden op fase scheiding,

ijzerkrullen in wikkelkopgedeelte statorwikkeling - Slechte ervaringen klanten - Bagatelliserende fabrikanten - Inadequate internationale standaarden - Noodzaak tot klantspecifieke specificatie

Opmerkelijke zaken: • Paper A1-109: Improved Generator Performance with a

Nanocomposite High Voltage Insulation System for Stator Windings – A Status Report

Omgaan met verandering van base load bedrijf naar cyclisch bedrijf ter voorkoming van vermeende versnelde veroudering van bestaand isolatiesysteem van grote turbogeneratoren:

Temperatuur statorwikkeling constant houden door regeling koeling

• Paper A1-111: Voith Hydro’s experience with the aging of insulation I.g.v. cyclisch bedrijf vertoonden staven geen versnelde veroudering in vergelijk met staven base load bedrijf

Paper A1-202 (Canada): Progress in Interpreting On-line Partial Discharge Test Results from Motor and Generator Stator Windings Poging om niveaus van PD te definiëren:

Distribution of Qm (mV) for air-cooled generators with 80 pF sensors

Paper A1-203 (Spain): Assessment of manufacture quality of stator windings insulation of rotating machines by means of macrographic analysis

Wat ontbrak c.q. is gemist: • Discussie over grid codes implicatie. Oorzaak: - Papers waren gericht op het vinden van oplossingen - Het ontbreken van vragen van de special reporters - 1 inbreng op de enige aan dit onderwerp gerelateerde vraag

• Wikkelkopvibratie. Oorzaak:

- Geen papers ingediend over dit onderwerp - Het ontbreken van vragen van de special reporters

Keynote addresses Planning criteria for future transmission networks in the presence of a greater variability of power exchange with distribution systems (John Wilson, UK) Interface & allocation issues in multi-party and/or cross-jurisdiction power infrastructures projects (Antonio Iliceto, Italy)

SC C1 – Open session

Planning criteria for future transmission networks in the presence of a greater variability of power exchange with distribution systems (John Wilson, UK) • What type of incentive could be implemented to ensure the effective sharing

of data between the TSO and DSO without introducing excessive regulation? • Are there sufficient incentives in place to drive technological innovation by

DSOs? • To what extent do DSOs know what services their customers actually want? • Are DSOs gearing up to handle ‘big data’? • Will TSOs continue to dispatch RES connected to the DSO network to the

same extent as today?

Keynote address 1/2

Interface & allocation issues in multi-party and/or cross-jurisdiction power infrastructures projects (Antonio Iliceto, Italy) • If the drop in electricity wholesale prices continues, it will necessarily start to

affect investment planning • Large subsidies for RES are distorting markets and affecting system

development planning • Concern was voiced that the burden of paying for RES subsidies

disproportionately affects SMEs (Small & Medium sized Enterprises)

Keynote address 2/2

Discussion focused on: • Monetization of risk

- how to value loss of life, reputation, etc - putting a value only when it’s a “common” value for all parties - becoming industry standard, so you cannot “not do it”

• Use of drones when inspecting a fleet of assets - good experience in Japan and Ireland for objective, better and cheaper insights - bad experience in UK to obtain license to fly, same as for TenneT

PS1: AssetManagement

Discussion focused on: • Uncertainty

- uncertainties relating to size, timing and location of RES • RES availability

- even intermittent RES have a predictability • Stakeholder engagement

- stakeholder engagement is key to the successful delivery of infrastructure • Market rules & Informing policy decisions

- realize the political reality which drives the paradigm changes, right or wrong! - TSO/DSO’s apolitical, but obligation to support informed political decisions - higher costs for ancillary services not accepted by regulators

PS2: planning T&D networks

Discussion focused on: • Low inertia

- concern on low inertia shared, but hope on Dublin and MIGRATE • Delivery of quality

- realize with offsite equipment instead of network enhancements; “VIP” treatment

• Organization - should planners and operators be split or together?

• More “controlling” equipment is being used - e.g. rotating transformer, STATCOM, VSC functionalities - AC and DC parallel lines operated with different filosophy

• Modelling - limitations discussed, both programs and skills of users

PS3: system solutions and techniques

Anticipate and plan a system that best fits the paradigm shift active WG:

SC C1 Strategic plan, vision and focus

PS 1 : Expanding role of social factors and transparency in transmission investment decision approaches • New elements in multi criteria evaluation • New stakeholders in the decision making process • Management of the scope of highly uncertain investments

PS 2: Impact of changing external factors on asset management • Political, economic, regulation, weather, cyber and physical security factors, etc. • Within-company strategy on grid modernization, e.g. monitoring, Big Data, asset analytics,

security • Asset usage and longevity effects from highly variable/non-schedulable generation

PS 3: Coordinated planning between grid operators across all voltage levels • Methodologies for planning multiple interconnected transmission grids and for transmission-

distribution interaction • How to share costs between different network utilities or adjust company organization and

strategy • The evolution of planning methods to account for smart grids, distributed generation, demand

response

C6 Session Distribution Systems and Dispersed

Generation

Irina Melnik (Alliander)

• Dispersed Energy Resources connection and integration

• DER concepts in distribution systems operation and planning

• Demand management and active customer integration

• Rural electrification

Scope of SC C6

Three preferential subjects were discussed in Session 2016: • PS1: Integrated planning and operation for upgrading distribution networks

• PS2: Energy infrastructure for urban networks

• PS3: Microgrids and off-grid hybrid systems

Preferential Subjects SC C6

Hot Topic: Need for a new planning methodology

High penetration of low carbon technologies

Network issues Tackled in the traditional way

- Costly assets - Underutilised assets - Inability to meet renewable targets

Key drivers for Active distribution network: • Environmental and regulatory pressure • Market liberalization and overall efficiency • Security of supply + increase quality of service • “Copper” investments postponement

• DSO’s still adopt traditional planning tools • Traditional planning is not suited for smart distribution • New planning methodologies are required

– Operation in planning – Include flexibility in planning – Data Modelling – Risk and reliability analysis – Cyber-physical simulation of ICT and Power Systems

Consequences for planning

at TSO’s?

How innovative are we with

planning methodologies

• In Multi-energy systems different sectors and networks such as electricity, heat, cooling, fuels, transport, water, and so on, optimally interact with each other.

• MES thinking: – Unlock technical, economic and environmental value hidden when

considering “classical” energy systems, treated “separately” or “independently” – Enable access to new forms of flexibility from various sectors to

guarantee a secure and affordable delivery of clean energy.

Hot topic: Multi-energy systems (MES) including heat, cooling, gas, water, and transport

Do we use advantages

of MES? • MES are particularly relevant in urban areas with the

potential to develop “Smart Communities” and “Smart Cities”.

• MES: – Could change load curves significantly for distribution networks; – May affect power quality, including voltage fluctuation and voltage deviation

caused by rapid load changes.

• Control technologies are needed to meet these challenges.

Hot topic: Multi-energy systems (MES) including heat, cooling, gas, water, and transport

Do we possess such technologies?

• How will dispersed generation typically affect network performance indexes such as SAIDI, SAIFI, LOEE?

• What measures will need to be considered to prevent network performance from degrading?

• One of possible solutions: Self-healing protection system consists of four steps:

– substation restoration, – priority feeder restoration, – feeder capacity change, – distribution system reconfiguration.

Hot topic: protection of grids with large amount of DG

Which other solutions do we see/use?

• Opening Panel. “Microgrids as contributors to energy security and system stability” • WG SC C6 'Microgrid Evolution Roadmap‘. First Technical brochure

Hot topic: Microgrids

• Definition of Microgrid. Two fundamental requirements: – the microgrid contains sources and sinks under local control; – can operate either grid-connected or islanded

• Two key types of microgrids should be distinguished : – Customer microgrids or true microgrids (μgrids) are selfgoverned entities, usually

downstream of a single point of common coupling. – Utility or community microgrids involve a segment of the legacy regulated grid, and are

called milligrids (mgrids). While not necessarily technically different from μgrids, they are fundamentally different from μgrids from a regulatory and business model perspective because they incorporate traditional regulated utility infrastructure.

Some of the key microgrid technology enablers: • Distributed energy resources plus load control. Distributed energy storage

(DES) allows: – to manage intermittent and renewable energy generation, – To serve load during islanded operation.

• Microgrid controls and supervisory systems: – to manage real time power balancing – to determine power exchange requirements with the megagrid during grid-

connected operation • Microgrid protection and automation:

– to ensure safe, sound, and autonomous operation of the microgrid internal assets,

– to fast detection and isolation faults.

Hot topic: Microgrids

How do we see the future

for Microgrids?

• PS 1 : Exploiting flexibility in strategic distribution planning and operation

– Managing resilience and congestion using distributed energy resources – Implementing demand response, customer empowerment and markets – Distributed resources asset management

• PS 2: Energy storage in distribution systems – Deploying and managing energy storage (electrical, thermal etc.) – Exploiting transportation electrification – Multi-energy system and load interaction for energy efficiency

• PS 3: Intelligent electrification for all – Electric energy systems for smart cities – Grid-connected microgrids – Off grid electrical systems for remote and rural deployment

• First findings of the WG 'Microgrid Evolution Roadmap'

WG 'Microgrid Evolution Roadmap'

• Definition of Microgrid. Two fundamental requirements: – the microgrid contains sources and sinks under local control; – can operate either grid-connected or islanded

Microgrids are electricity distribution systems containing loads and distributed energy resources,

(such as distributed generators, storage devices, or controllable loads) that can be operated in a

controlled, coordinated way either while connected to the main power network or while islanded.

• Two key types of microgrids should be distinguished : – Customer microgrids or true microgrids (μgrids) are selfgoverned

entities, usually downstream of a single point of common coupling. – Utility or community microgrids involve a segment of the legacy

regulated grid, and are called milligrids (mgrids). While not necessarily technically different from μgrids, they are fundamentally different from μgrids from a regulatory and business model perspective because they incorporate traditional regulated utility infrastructure.

1. Definition and Clarification of Microgrid Concept

• Microgrid Stakeholders with a direct financial interest are: – the microgrid owner or operator, – the distribution network operator, – participants in the microgrid, – those who may be directly affected by the existence of microgrids, etc.

• Ownership models: – ownership by the distribution network operator (DNO), – ownership by a current customer or consortium of customers, – independent ownership.

In each case, the microgrid would tend to operate so as to maximise the benefit of the owning stakeholder.

2. How can a Microgrid become profitable? Who owns and/or operates it?

• Distributed energy resources (DER): generation, energy conversion and storage, plus load control.

– Distributed energy storage (DES) allows: • the management of intermittent and renewable energy generation, • serving load during islanded operation.

• Microgrid controls and supervisory systems: – to manage real time power balancing – to determine power exchange requirements with the megagrid during grid-

connected operation • Microgrid protection and automation:

– to ensure safe, sound, and autonomous operation of the microgrid internal assets,

– to fast detection and isolation faults.

3. Some of the key microgrid technology enablers

• Drivers – Exploiting the full benefits of integration of large numbers of small-scale

DER – Resilience has been a dominant concern in the northeastern U.S. and Japan,

following those areas' recent natural disasters. – Off grid electrical systems for remote and rural deployment

• Advantages to customers and utilities: – improved energy efficiency, – minimisation of overall energy consumption, – reduced environmental impact, – improvement of reliability of supply, – network operational benefits such as loss reduction, congestion relief, voltage

control, security of supply, and more cost-efficient electricity infrastructure replacement.

4. Why are Microgrid needed? Benefits of Microgrid

• Cost-benefit analysis requires all impacts be classified into two categories: – “known impacts,” which must be known a priori – and “discovered impacts,” which must be found through simulation or

calculation. • Direct Benefits

– The direct beneficial technical and economic impacts classified as improved efficiency, reduced emissions, and improved power quality and reliability.

– Economic benefits can be obtained through the participation of microgrid loads and sources as one co-operating entity.

• Indirect Benefits – Difficult to quantify. They include environmental benefits such as a reduction in

emissions of greenhouse gasses and other pollutants, reduction of the physical footprint required for power generation, reduction of reliance on external fuel sources and prices, and the creation of employment.

5. Advantages of wide deployment of Microgrids

Necessary equipment and methods needed to deploy a Microgrid: • establishment of a business case, • assembling and configuring of available technology for controlling local generation

and loads, • development of a mutually beneficial interaction with the wider legacy electric

power system (or megagrid), from both the operations and market perspectives under the prevailing regulatory environment.
