In this paper, a new local quadratic wavelet neural network (LQWNN) method is proposed for short-term wind power generation prediction in power system. Due to the nonlinear structure of its local quadratic model (LQM), this method can effectively simulate the nonlinear behavior of wind power generation. In the time domain and frequency domain, wavelet function sets the effective region of LQMs in LQWNN, thus improving the learning efficiency and structural transparency of the overall model. The proposed LQWNN method employs a simple and effective particle swarm optimization (PSO) algorithm and optimizes its parameters. Through two real cases studies, namely the wind power forecast of the Irish power grid and the Jiuquan wind power plant in Gansu province, the performance of the proposed wind power forecasting method is evaluated and compared with other methods. The results show that the LQWNN method proposed in this paper is very effective in predicting wind power generation and has a good application prospect.
