10 Cross Sintra Seminar May Smartgrids 10 Examples from CIRED Authors

11 Cross Sintra Seminar May Smartgrids 11 Active Networks Load Management in a UK Registered Power Zone Significant amounts of wind generation are under construction in the area surrounding Skegness including both off-shore and on-shore developments. Most of this generation needs to be exported from Skegness to Boston via an existing dual circuit (1x175mm 2 ) 132kV tower line. If conventional Winter/Summer ratings were applied it would be impossible to connect all the proposed wind generation as this circuit would be overloaded Solution is to apply a dynamic line rating to the circuit based on real-time ambient temperature and wind speed data Generation increases as wind speed increases but the corresponding increase in cooling from the same wind combine to improve the rating of the circuit by 20-30% All data is being captured and recorded to allow for verification and refinement of the process adopted This scheme will have benefits for other parts of the network where circuits existing conventional ratings are also apparently approaching their theoretical limits. R. Ferris – UK - Paper 0038 CIRED Smartgrids Seminar

12 Cross Sintra Seminar May Smartgrids 12 Impact of Microgrids concept on low voltage network reliability Detailed analysis of basic impacts of dispersed generation (DG) such as wind turbines, PV–systems and CHP units on network reliability Demonstrated how a suitable Microgrid operation strategy with corresponding control and protection schemes may improve total network reliability for different customer segments Traditionally time-dependent limited availability is neglected for the determination of network reliability indices assuming a fixed operating point for DER with reduced availability corresponding to the percentage of full load hours of the generation technology (i.e. 10 % for PV) An advanced approach which considers the synergy of time-dependent load profiles and generation profiles for an analytical reliability evaluation is described Potential for DG impact on reliability was analyzed for various DG penetration scenarios differentiated by location, capacity, number & type Simulation results for three cases (1) without DG, (2) with uncontrolled DG (island operation mode) and (3) with Microgrid operation compared Difficulties in adequate simulation that result from the complexities of meshed network structures are pointed out. However, the available results indicate that DG improves reliability - especially when controllable units are installed Christine Schwaeger– Germany - Paper 0027 CIRED Smartgrids Seminar

13 Cross Sintra Seminar May Smartgrids 13 Virtual Power Plant Field Experiment using 10 micro-CHP units at Consumer Premises B. Roossien– Netherlands - Paper 0086 CIRED Smartgrids Seminar The experiment focused on the network utilization factor of the local distribution grid in 3 settings: 1.Baseline: domestic load profile of 10 households. 2.Fit-and-Forget: load profile of 10 households plus mCHPs controlled in standard heat-demand driven manner 3.VPP operation: mCHP operation coordinated by PowerMatcher intelligent control in peak-load reduction mode, without any intrusion on comfort for consumers. The main conclusions from these experiments are: A Fit-and-Forget policy did not provide benefits to the DNO in comparison to the baseline case. The load-duration curve was lowered on average by adding the m-CHPs. However, the peak load remained virtually unchanged. Adding VPP operation, based on intelligent control, led to a load-peak reduction of 30% in summer and 50% in winter.

14 Cross Sintra Seminar May Smartgrids 14 Application of energy storage systems - minimizing effects of fluctuating feed-in of photovoltaic systems Up to now the installation of plant storages to smooth the feeding is uneconomic The main reason is the law (EEG) which assures operators of renewable energy generator fixed feed-in tariffs for energy supply into the power grid. The feed-in does not have to fit the current electrical demand If the EEG would guarantee just a fixed feed-in tariff for generation which are applied a day before, renewable energy generators with energy storage systems may establish. Also feed-in tariffs which depend on the feeding-profile may lead to a market penetration of storage systems installed at distributed generators Fig. 1: Application of a plant storage system (PS) to a PV unit G. Bärwaldt – Germany - Paper 0112 CIRED Smartgrids Seminar

15 Cross Sintra Seminar May Smartgrids 15 InovGrid Project – Distribution network evolution as a decisive answer to new electrical sector challenges Technical architecture being developed for the implementation of a fully active distribution network Energy Boxes (EB) nearest devices to consumers and producers, will support all metering and contractual life-cycle related services, also delivering through local communications detailed information & support message exchange and, where applicable, support micro-generation management and control Distribution Transformer Controllers (DTC) housed at MV/LV substation level, that besides managing services and communication with EB, operate as intelligent devices for transformer station control & automation, for fault detection and also for public light management Phase 2 includes developments in the areas of active distribution networks, self- healing, micro-generation control strategies to deal with islanded operation and to help in power system restoration after exploitation problems and blackout situations, network assets monitoring, automation and control, and demand response and side management techniques L. Vale da Cunha – Portugal - Paper 0030 CIRED Smartgrids Seminar

Corera – Spain – RT4c CIRED 2007

17 Cross Sintra Seminar May Smartgrids 17 Norwegian Electricity Customers Attitudes Towards Smart Metering Willingness to pay is higher among those who currently have smart metering (39%) than those who do not (27%) Confidence in smart metering is high; 70% believe that it is as accurate as manual meter reading The proportion of sceptics is gradually falling Interest in using associated services is moderate E. Fosby – Norway - Paper 0052 CIRED Smartgrids Seminar

18 Cross Sintra Seminar May Smartgrids 18 A Roadmap for Developing Real Time Distribution System Simulation Tools for the Smart Grid Simulation capabilities available to the operators play an important role in Smart Grid improvements by providing new perspectives on network operation with new possibilities for what if analyses and on network development with more accurate models However, the opportunities for new developments in simulation capabilities are very broad and efforts have to be strongly correlated to network operator needs and identified technical improvement pathways in order to be sure of their effectiveness A survey of the main experts of the industry was conducted to: –identify the main drivers of tool evolution –determine the most likely path for evolution of simulation and modelling functionalities The results of this roadmap are intended to provide a high level view of the functionalities that will be needed in the next 10 years to allow SmartGrids operation X.Mamo – USA - Paper 0021 – CIRED Smartgrids Seminar

19 Cross Sintra Seminar May Smartgrids 19 Active Network Management: Technical, Commercial & Regulatory Barriers The following are likely to find most application in ANM –FACTS devices (eg SVCs) –MicroGrid Controllers –SCADA The equipment associated with these ANM techniques are currently available in the marketplace from a number of manufacturers and little development work will be required to make these equipments available for widespread use Currently there is little penetration of ANM into UK distribution networks and the tools used by DNOs to plan and develop their networks generally do not include ANM techniques as options for network development Accordingly the lack of familiarity of the use of ANM techniques by DNO planners could be a barrier to ANM as the more traditional tried and tested solutions tend to used G.D.Clarke – UK - Paper 0122

20 Cross Sintra Seminar May Smartgrids 20 Barriers to smart grids cultural barriers costs of development and implementation high levels of uncertainty regulatory risk perceived complexity risks from Cyber crime burden of operating and maintaining the solutions vested interests C.Walton – UK - Paper 0026 CIRED Smartgrids Seminar Having established the case for smart grids the paper examines reasons why they may not happen other than in small splashes of limited functionality. Potential barriers that are examined include:

21 Cross Sintra Seminar May Smartgrids 21 The route to smart grids regulatory frameworks suitable incentives that support appropriate investment increased emphasis on research and development collaboration within industry and between industry and academia recognition of the need to get demonstration projects into place planning for large-scale rollout putting into place standards the importance of ensuring interoperability need to validate that these complex systems are effective and safe C.Walton – UK - Paper 0026 CIRED Smartgrids Seminar Finally we suggest some actions to make it more likely that smart grids will emerge and take their place in the future energy world. In other words, what we need to do to make them happen. These include

22 Cross Sintra Seminar May Smartgrids 22 Smart Grids: on the road to reality the sector is facing a paradigm shift, not a variant of existing classical grid practices the sector is facing the biggest change in 40 years of grid development there is no simple blueprint, but there is an emerging vision and common concepts there are many stakeholders involved, each with critical roles to fulfill with multiple stakeholders involved, who is going to lead and co- ordinate what is required, beyond the technology, for successful implementation of smart grids J.Scott – UK - Paper 0097 CIRED Smartgrids Seminar Key messages are as follows: Key conclusions are: 1.This is a revolution, not a variation on a theme 2.The span of business impacts must be addressed, not just the technology 3.There are management issues to be identified and addressed

23 Cross Sintra Seminar May Smartgrids 23 Some Personal Views Distribution Network Operators are now commercial regulated businesses in most countries => They require incentives to grasp innovation & take risks Many SmartGrid applications have benefits that sprawl across DNO, TSO, generator, retailer, customer and community => Unbundling makes these more difficult to realise and reduces their attractiveness Impact of IFI Incentive Privatisation UK Distribution Company spend on Network R&D since 1990

24 Cross Sintra Seminar May Smartgrids 24 In Conclusion There are powerful drivers taking us towards smarter or more intelligent networks Many smart grid technologies are in development with some available to deploy Implementation requires significant investment if it is to make an impact Regulatory acknowledgement is needed However, there is still plenty of work for the research, development, system builder and implementation communities in both T & D
