Dielectrische eigenschappen beduidend slechter dan van SF 6 -gas, met name voor het onderbreken van stromen. Verder is er nog weinig over gepubliceerd. LCA is veel beter dan met SF 6 -gas, maar feitelijk nog onvergelijkbaar.
34 A3-109: KEMA-HPL Test circuit met 17 Hz om DC foutstroom onderbreking te simuleren met voldoende MW-power. DC stroomonderbreking leidt tot overhevelen van magnetische energie (½LI²) naar elektrische energie (½CU²), waardoor zeer hoge overspanningen ontstaan, die door MOSA begrenst moeten worden en waarbij de energie gedissipeerd. Anderen stellen two-part-test voor waarbij MOSA apart beproefd wordt. A3-106 en A3-117 tonen alternatieve schakelaar technologiën; A3-112 een speciale MOSA

138 SC C1 Open session Preferential subjects 2016 PS1: making PS2: PS3: State of the art approaches and standardization in Asset Management decision 5 papers Interface and allocation issues in planning T&D networks with multi-party projects 6 papers New system solutions and planning techniques for flexible and robust system plans 23 papers 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)
139 Keynote address 1/2 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?
140 Keynote address 2/2 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)
141 PS1: AssetManagement 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
142 PS2: planning T&D networks 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
143 PS3: system solutions and techniques 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

199 Preferential Subjects 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
200 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
201 Hot Topic: Need for a new planning methodology 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 Consequence s for planning at TSO s? How innovative are we with planning methodologies?
202 Hot topic: Multi-energy systems (MES) including heat, cooling, gas, water, and transport 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. MES are particularly relevant in urban areas with the potential to develop Smart Communities and Smart Cities. Do we use advantages of MES?
203 Hot topic: Multi-energy systems (MES) including heat, cooling, gas, water, and transport 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. Do we possess such technologies?
204 Hot topic: protection of grids with large amount of DG 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. Which other solutions do we see/use?
205 Hot topic: Microgrids Opening Panel. Microgrids as contributors to energy security and system stability WG SC C6 'Microgrid Evolution Roadmap. First Technical brochure 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.
206 Hot topic: Microgrids 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 gridconnected operation Microgrid protection and automation: to ensure safe, sound, and autonomous operation of the microgrid internal assets, to fast detection and isolation faults. How do we see the future for Microgrids?

213 WG 'Microgrid Evolution Roadmap' First findings of the WG 'Microgrid Evolution Roadmap'
214 1. Definition and Clarification of Microgrid Concept 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.
215 2. How can a Microgrid become profitable? Who owns and/or operates it? 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.
216 3. Some of the key microgrid technology enablers 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 gridconnected operation Microgrid protection and automation: to ensure safe, sound, and autonomous operation of the microgrid internal assets, to fast detection and isolation faults.
217 Drivers 4. Why are Microgrid needed? Benefits of Microgrid 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.
218 5. Advantages of wide deployment of Microgrids 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.
219 Conclusions 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.
