Optimal Active Power Flow Considering Uncertainties of Wind Power Output and Load
摘要
Abstract
An optimal active power flow model, in which the uncertainties of wind power output and load are considered, is established. In allusion to the poor adaptation of spinning reserve capacity determined by traditional experience method, that is needed by power system, based on the interval prediction of wind power output and load demand the positive-and negative-spinning reserve capacity determined by extreme scenario theory is used to coordinate the randomness of wind power output and load. To remedy the defect that in existing unit ramp rate constraint only single single-period unit regulation is considered and to avoid the regulation of units exceeds the limit while abrupt fluctuations of wind power output and load occur, multi-period coupling constraints are added to balance the fluctuation between wind power output and load. An improved particle swarm optimization algorithm is utilized to solve the proposed model and the correctness and effectiveness of the proposed model are verified by simulation results of IEEE 30-bus system with wind farms.关键词
