  1. SMART GRID – DEVELOPMENT OF ELECTRICAL GRID FOR RES INTEGRATION Stefan Apostolov, CEZ Bulgaria EAD Sofia, October, 2010

  2. NEW CHALLENGES IN FRONT OF ELECTRICITY GRID • Separation of activities vertically • Energy markets liberalization • New requirements for quality of services • Goals 20/20/20 • Renewable energy resources • Energy efficiency • Reduce CO2 emissions • Distributed generation

  3. TRIPPLE BALANCE IN EUROPEAN ENERGETICS Availability of energy resources Market liberalization Innovations and competitiveness Reliability and quality Security of supply Market of electricity Low prices and efficiency New powers • Environment Nature conservation Climate changes Pollution

  4. INTEGRATION OF WIND POWERS • Turning wind into basic power • Reducing dependence on imported resources • Hedge against future higher costs for CO2 • Grid parity – when prices will not be different • Germany’s example in “pacifying” the wind

  5. RES IN BUILDINGS AND EQUIPMENTS • Two-way electrometers and possibility for sale • Increasing energy efficiency class • Stimulating direct use of RES • Reducing transmission at the expense of local use of energy (micro grids) • Initial investment for further cost reduction – possibility for ESCO schemes • Preferential rates or single grant?

  6. ELECTRIC POWER AND TRANSPORT • Tool for storage green energy and provide reserve • Using night-rate energy • Reducing dependence on imported resources • Reducing emissions from transport • Successful conversion of company cars • Examples: Berlin, Paris, Rome…

  7. THE EXAMPLE OF DENMARKS AND CONTRIBUTION OF GERMANY AND SCANDINAVIA Centralized system in 90’s Decentralized system of today

  8. SMART GRID – WAY FOR INTEGRATING RES IN GRID Smart Grid • ICT • Billing • CRM • ERP • GRID INTELLIGENCE • Automatization • Asset Management • Protection • Monitoring • AMR* systems • Electrometers Transmission grid Distribution grid *AMR: Auto meter reading

  9. SMART GRID RISKS • NecessaryICT support for functionalities • ICT network reliability • Protection of information ICT • No legal frame • Cost recognition - return • Lack of unified solutions and expensive interface of available systems Regulation and standardization Supply • Risks in supplies • Three parties in process – supplier, consumer and producer • Lack of “Smart grid” frame • Contradictions of pilot projects • No clear results after investment • Lack of knowledge in clients and personnel Others

  10. SMART GRID GIVES NEW POSSIBILITIES Market Clients • АММ , information portal, smart home • New tariff structure and logic (preliminary payment and others) Tariffs Consumption audit • Trade analysis of clients’ behaviour, consulting RES and E-vehicles • Integration and optimization of use • RES centralized management and optimization Virtual Plants Regulation • Monitoring of the grid • Reducing disconnections • Consumption control – ability of network • Better “fill” the network Distribution

  11. STEPS FOR IMPLEMENTING SUCCESSFUL PRACTICES • Selecting possibilities for new pilot projects • Solving the most pressing problems • Investments in innovations and technologies • Support from Regulatory Commission for covering the necessary • investments expenditures • Communication with clients for advantages of smart grid • Micro-grid development
