Abstract

Volatility and randomness of wind speed and solar irradiance can make it difficult to predict the power of wind and photovoltaic in short time, which reduces power grid’s scheduling ability and affects the stability of grid-connected operation of new energy power generation. In order to address this problem, the Quantum Particle Swarm Optimization (QPSO) algorithm is adopted to optimize the network structure and parameters of Long-Short Term Memory (LSTM) net-work. Through theoretical analysis of working principle and process of LSTM network and optimization algorithm, an optimized LSTM for predicting wind and photovoltaic power in short time is established. The accuracy of the proposed model is proved by using actual data, then compared with unoptimized model and particle swarm optimization (PSO) optimized model. The results of experimental indicate that the LSTM model optimized by QPSO has better prediction precision and demonstrates good prediction results in both wind and photovoltaic power generation in short time, with a wider applicability.
