Evaluation Method on Capacity Credit of Generalized Power Source in High Voltage Distribution Network

In active distribution network, the access of distributed generator, energy storage system and demand-side controllable load improve the system reliability, and can serve part of load supplied by the high voltage distribution network. In order to evaluate the capacity value of the generalized power source, an evaluation method for the capacity credit of the generalized power source in high voltage distribution network is proposed according to the principle of equal reliability. The secant method and the state transfer sequential Monte Carlo method are used to solve the problem. The credible capacity of generalized power source is analyzed under a variety of high voltage distribution network typical connection configurations in the case study. The quantitative result verifies the validity of the proposed method and provides a reference for the active distribution network substation capacity planning and the network structure configuration selection.
