A strategy of minimising wind power curtailment by considering operation capacity credit

An optimal wind power curtailment strategy considering operation capacity credit is proposed in this paper to minimize the uncertain wind power curtailment and minimize the system operation cost. The relevant definitions in capacity credit assessment are applied in the power system operation situation. Based on operation capacity credit prediction, the optimal operation control strategy is defined and implemented for hourly system operation and control. Multi-agent system based control structure is adopted to coordinate the diverse system components to work together and realize the system wide targets of the proposed strategy. The simulation results demonstrate the effectiveness of the proposed strategy.
