Calculation of wind-farm capacity credit based on probabilistic production simulation and its application

In aspect of capacity, wind power generation and traditional power generation is inner connected. The capacity credit is a convenient and effective way to compare these two different types of power generation. Capacity credit of wind power (CCOWF) is presented in this paper, as well as a calculation method of CCOWF based on probabilistic production simulation (PPS), this method is based on sequence operation theory (SOT) and considers both the probabilistic of load and power generation. Considering the loss of load expectation (LOLE) is unchanged with the accessing of wind power and shutting some gas-guzzling thermal power down. The corresponding software is programmed, and the diagrammatic method is developed to calculate and the CCOWF of IEEE-RTS79 test system. In the end, the application of CCOWF in aspect of calculating the ability of peak load regulation and the capacity of spinning reserve is short presented.
