Wind Power Penetration Limit Calculation Based on Stochastic Optimal Power Flow

This paper presents a calculation method of wind power penetration limit based on stochastic optimal flow. Aiming to maximize wind power integrated into the system while taking power flow equation and security constraints into consideration, a mixed integer nonlinear programming model with multi-variables including random ones and multi-constraints is proposed utilizing chance constrained programming due to the random feature of wind speed. A particle swarm optimization algorithm based on stochastic simulation technique is employed to solve this model. Simulation of the IEEE 30-bus test system validates the feasibility and correctness of the proposed model and some limiting factors which impact wind power penetration limit are also analyzed to put forward suggestions on the planning of wind farm.
