SMART GRID – DEVELOPMENT OF ELECTRICAL GRID FOR RES
INTEGRATIONStefan 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

Market liberalization
Innovations and competitiveness
Low prices and efficiency
Availability of energy resources
Reliability and quality
New powers
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…

SMART GRID RISKS
Supply
Regulation and standardization
Lack of “Smart grid” frameContradictions of pilot projectsNo clear results after investmentLack of knowledge in clients and personnel
Others
Necessary ICT support for functionalities ICT network reliability Protection of information
No legal frame Cost recognition - return Lack of unified solutions and expensive interface of available systems
Risks in suppliesThree parties in process – supplier, consumer and producer
ICT

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

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
