SECI REGIONAL TRANSMISSION SYSTEM PLANNING GROUP • HISTORY • SOUTHEAST EUROPE COORDINATION INITIATIVE – 1998 • REGIONAL TRANSMISSION SYSTEM PLANNING PROJECT (USAID) – 2001 • ALBANIA, BULGARIA, BOSNIA AND HERZEGOVINA, CROATIA, FYROM, MONTENEGRO, ROMANIA, SERBIA, UNMIK • TURKEY, SLOVENIA, ITALY • MODELS FOR 2005, 2010, 2015 AND 2020: PSS/E FORMAT, STEADY STATE, DYNAMIC, SHORT-CIRCUIT (WINTER PEAK, SUMMER OFF-PEAK) • STUDIES • REGIONAL ELECTRICITY INTERCONNECTION STUDY – 2002 • GENERATION INVESTMENT STUDY (GIS): PSS/E ANALYSIS AND RESULTS – 2004 • TRANSMISSION NETWORK INVESTMENT CRITERIA – 2007 • EVALUATION OF INVESTMENTS IN TRANSMISSION NETWORK TO SUSTAIN GENERATION AND MARKET DEVELOPMENT IN SEE – 2007
TRANSMISSION NETWORK PLANNING • VERTICALLY INTEGRATED UTILITIES • INTEGRATED PRODUCTION, TRANSMISSION AND DISTRIBUTION PLANNING • OPTIMIZATION ON NATIONAL LEVEL • AVAILABLE DATA • UNCERTAINTIES (LOAD GROWTH, HYDROLOGY, GENERATORS AND NETWORK AVAILABILITY) • OPEN MARKET ENVIRONMENT • REGULATED TRANSMISSION ACTIVITIES • SEPARATED COMPANIES • MARKET TRANSACTIONS (UNPREDICABLE FOR A LONG-TIME FRAME) • SECURITY VS. ECONOMIC EFFICIENCY • PLANNING ABOVE NATIONAL LEVEL (COORDIATION BETWEEN TSOs) • UNCERTAINTIES (POWER PLANTS CONSTRUCTION AND DISPATCH, ELECTRICITY PRICES, MARKET TRANSACTIONS, REGULATORY REQUESTS, ENVIRONMENTAL ISSUES etc.)
TRANSMISSION NETWORK PLANNING – cont. • EXPERIENCES IN THE SEE • 9 TSOs • NATIONAL GRID CODES • LACK OF REGIONAL GRID CODE • DIFFERENT PLANNING CRITERIA (HARMONIZATION IS NEEDED) • MARKET ISSUES - NOT SATISFACTORY TREATED • PLANNING CRITERIA AND METHODOLOGY • MOSTLY USED (N-1) TECHNICAL CRITERION • LACK OF ECONOMIC CRITERIA • POWER SYSTEM SIMULATIONS, MULTI-SCENARIO ANALYSES • SECI STUDY “TRANSMISSION NETWORK INVESTMENT CRITERIA” – SUGGESTION OF COMMON TECHNICAL AND ECONOMIC CRITERIA FROM REGIONAL PERSPECTIVE • TRANSMISSION PROJECTS PRIORATIZATION FROM REGIONAL PERSPECTIVE
UNCERTAINTIES IN A TRANSMISSION NETWORK PLANNING New situation 1 – different generators bidding behavior Initial situation – overloading of the line 1-2 (transmission capacity of all lines 300 MW) New situation 2 – new generator in the node 2
UNCERTAINTIES IN A TRANSMISSION NETWORK PLANNING – SEE POWER SYSTEMS • THE MOST IMPORTANT UNCERTAINTIES: • UNKNOWN POWER PLANTS SIZE AND LOCATIONS • LOAD GROWTH • WIND FARMS • FUTURE MARKET TRANSACTIONS • UNKNOWN GENERATORS DISPATCH • ELECTRICITY PRICE What is the most influential uncertainty in your country related to a transmission network planning?
STUDY ON PLANNING UNCERTAINTIES IN THE SEE TRANSMISSION SYSTEM • OBJECTIVES : • IDENTIFICATION OF THE MOST IMPORTANT UNCERTAINTIES IN EACH SEE COUNTRY • ANALYSIS AND EVALUATION OF IMPACT OF DIFFERENT UNCERTAINTIES ON PLANNED TRANSMISSION INVESTMENTS AND SEE TRANSMISSION SYSTEM. • SCENARIOS (73): • POWER PLANTS CONSTRUCTION PLAN • CONNECTION OF ITALIAN MARKET WITH SEE MARKET • CONNECTION OF TURKISH MARKET WITH SEE MARKET • INDIVIDUAL COUNTRIES POWER BALANCE • BRANCHES AND GENERATORS AVAILABILITY • PLANNING TIME FRAME
STUDY ON PLANNING UNCERTAINTIES IN THE SEE TRANSMISSION SYSTEM – cont. • POWER PLANTS CONSTRUCTION PLAN: • TPP KOSOVO C (2120 MW) • NPP KRŠKO 2 (1080 MW) • PSHPP KOZJAK (440 MW) • WPPs IN B&H, CROATIA, SERBIA, MONTENEGRO, ROMANIA, BULGARIA (4600 MW) • CONNECTION OF ITALIAN AND SEE MARKETS: • HVDC ALBANIA – ITALY (1000 MW) • HVDC MONTENEGRO – ITALY (1000 MW) • HVDC CROATIA – ITALY (1000 MW) • CONNECTION OF TURKISH AND SEE MARKETS: • HVDC TURKEY – ROMANIA (1000 MW)
STUDY ON PLANNING UNCERTAINTIES IN THE SEE TRANSMISSION SYSTEM – cont. • COUNTRIES POWER BALANCE: • ALBANIA (ZERO BALANCE, EXPORT) • BOSNIA AND HERZEGOVINA (ZERO BALANCE, EXPORT) • BULGARIA (ZERO BALANCE, EXPORT) • CROATIA (ZERO BALANCE, IMPORT) • MACEDONIA (ZERO BALANCE, IMPORT) • MONTENEGRO (IMPORT, EXPORT) • ROMANIA (ZERO BALANCE, EXPORT) • SERBIA (ZERO BALANCE, IMPORT) • SLOVENIA (ZERO BALANCE, EXPORT) • TURKEY (IMPORT, EXPORT) • UNMIK (ZERO BALANCE, EXPORT)
STUDY ON PLANNING UNCERTAINTIES IN THE SEE TRANSMISSION SYSTEM – cont. • IMPACT OF UNCERTAINTIES ON TRANSMISSION INVESTMENTS 2015:
STUDY ON PLANNING UNCERTAINTIES IN THE SEE TRANSMISSION SYSTEM – cont. • IMPACT OF UNCERTAINTIES ON TRANSMISSION INVESTMENTS 2020:
STUDY ON PLANNING UNCERTAINTIES IN THE SEE TRANSMISSION SYSTEM – cont. • THE MOST CRITICAL LINES AND TRANSFORMERS IN THE REGION • OHL 220 kV DIVACA (SLO) – PADRICIANO (I) • OHL 220 kV PEHLIN (HR) – DIVAČA (SLO) • TR 400/220 kV TREBINJE • OHL 220 kV ZAKUCAC (HR) – IMOTSKI (HR)/RAMA (BIH) • TR 400/220 kV MARITZA • OHL 400 kV CONSTANTA – CERNAVODA • TR 400/220 kV ROSIORI • OHL 220 kV UNGEHENI - IERNUT
CONCLUSION • SEE REGIONAL TRANSMISSION SYSTEM DEVELOPMENT: • STRONG INTERCONNECTIONS EVEN TODAY • CONGESTION MANAGEMENT – COORDINATED AUCTIONING – HIGHER NTC VALUES • INTERNAL NETWORK REINFORCEMENTS • NEW PROJECTS IF TECHNICALLY AND ECONOMICALLY FEASIBLE • STRONGER REGULATORY AGENCIES • INDEPENDENT TSOs • COORDINATION IN PLANNING • HARMONIZATION OF PLANNING STANDARDS
