OPTIMAL REAL POWER FLOW IN WIND POWER INTEGRATED SYSTEM

An algorithm for calculating optimal active power flow based on chance-constrained programming for wind power integrated system is proposed. The randomvariables are introduced to represent wind farm outputs and buses loads. Acco rdingly, the constraints like branch power flow, bus voltage, spinning reserve and steady frequencydeviation are expressed by means of probability. To solve the problem, a calculation program implementing geneticalgorithm and stochastic simulation are developed, the testresults on IEEE30 system demonstrate the feasibility of the proposed model and algorithm.
