Comparison of Centralized Market-Based Dispatch of Flexibility Options at Distribution Network Level with Regional Balancing Strategies in the German Power System - (PPT)

摘要

The majority of demand and supply needs a transmission grid for balancing. Decentralization as control strategy leads to higher variable generation costs: more expensive generation and less efficient flexibility options come into the market. The less expensive generation capacities not needed for covering demand any more start producing for export. Decentralized flexibility options need additional incentives due to the reduced local merit order. Centralized dispatch including perfect foresight and neglecting unit specific restrictions overestimate flexibility.
