apidly in Europe due to the European legislation. At the moment countries are in different stage:some countries have already almost 100 % penetration and some are in the experimental phase.Cost-benefit analyses show in most cases that smart metering is in most cases economically feasibleif the benefits to all stakeholders and to society is taken into account. It seems to be important todevelop standardization and functional requirements to such a directions that all the benefits fromDER can be obtained. Some smart meters can already be used for simple control of DR resources.8.2 Stakeholder involvement and effectsMicrogeneration and new end-use technologies can present significant effects to severalstakeholders. Most importantly, the consumer himself, network companies and electricity supplier(retailer) are involved. Network companies may either benefit or suffer from the introduction ofmicrogeneration, heat pumps and EV, depending on the specific technology and how it is used. Theconsumer can contract an aggregator to sell the microgeneration or load flexibility to competitiveenergy market participants or network companies. Manufacturers strive to develop more affordableand more efficient generating units, normally with the help of subsidies provided by governments.The stakeholders can effect on the penetration with differ ways. New market models and businessmodels have been developed and should be develop further.In each case the costs and benefits to each stakeholder depend on the details of technologies andtheir methods of control, as well as on the details of contracts between stakeholders. For example,microgeneration may in some cases benefit DSO in the form of reduced peak load but the negativeeffect on revenue may be much larger. Thus the specific tariff applied has a crucial effect.Similarly, the financial incentives applied between an aggregator and consumer have a crucial effecton the benefits and behaviour of both parties.It is important that in each case the key parties involved should find rules, tariffs and incentives,which in spite of common benefits also allow all stakeholders to benefit, or at least not suffer, fromthe introduction of the new technologies. Otherwise it will be difficult to form successful businessmodels on voluntary basis. To implement DR with the new technologies, appliance manufacturersshould add machine-to-machine communication ability using widespread open standards.The quantitative assessment of e.g. network effects of new technologies is very much dependent onthe case to be studied (local network situation and architecture, customer mix, penetration scenarios,regulatory environment etc.). It is difficult to generalize results from one case to another.8.3 Proposal for the future workOn the basis of the work carried out in Phase 1 and 2 it is proposed to continue the work in Phase 3.Very preliminarily this phase includes four new subtasks:8.3.1 Subtask 10 – Role and potentials of flexible consumers (households andbuildings)ObjectivesAssessing the concepts and implementations of customer energy management systems (CEMS) indifferent (participating) countries:- Comparing specific requirements in households vs. functional (office) buildings- Energy balancing possibilities and potentials- Role of Smart Meters (SM) and (CEMS) – in the terms of technical concepts27
Technologies:In order to enable DSM, existing functionality and requirements of SM and CEMS according to thespecifications (M/441, country specific) will be analyzed as following:- Local balancing / local markets of the generated power/energy with the consumption- Controlled charging and discharging of EV- Integrating electrical storages- Support aggregation to participate in markets and grid operation.Providing network user's flexibilities [10]8.3.2 Subtask 11 – Changes and Impacts on the grid and market operationObjectives:Quantification of impact on grid and market operation based on technology penetration scenariosdeveloped in subtask 5.- Improvement on grid operation- Customer benefits- Optimization potentials- Methodology to estimate potential and to cost effective activation.- Regulation issues for grid and (local) market operationsInteraction:How do CEMS interact with flexibility operators (aka. aggregators)?- Impact on the grid operation (technical flexibility)- Impact on the market (market flexibility)- Technical feasible but optimization necessary:- Requirements for establishing this grid operating and market mechanisms? – regulatory andlegislative- Installation and operation costs vs. delayed network investments.28
