基于虚拟电厂调控的分布式新能源与小水电群互补发电研究
Complementary Power Generation of Distributed New Energy and Small Hydropower Group Based on Virtual Power Plant Regulation
摘要
Abstract
In view of the importance and potential of small hydropower in the energy system,the output characteristics and scheduling optimization of small hydropower are studied,and a multi-objective optimization model of small hydropower-wind-photovoltaic combined system is constructed with the objective function of maximizing the tariff revenue,maximizing the rate of new energy consumption,and minimizing the difference between the peaks and valleys of loads,and taking into account the peak-valley time-sharing tariff and the constraints related to hydropower and new energy sources.Taking Qinghai Power Grid as an example,different virtual power plant aggregation schemes are set up considering the geographical location of each energy source and new energy source conditions,and three operation strategies are set up to evaluate the regulation capability of the combined system under very high new energy ratio.The results show that after the virtual plant aggregation,the combined generation system's tariff revenue,new energy consumption rate,and load peak-to-valley difference on typical days are all improved.The research method can provide a new method for the short-time and long-time fine regulation of small hydropower group and distributed new energy complementary power generation.关键词
