摘    要:为解决大规模间歇性能源的不确定性和波动性给电网的发电计划制定和调度带来的问题,针对风电、光伏等的出力波动性强和电网负荷波动明显,提出了风光蓄一体化出力的调度策略,定义了广义负荷的概念,利用抽水蓄能的灵活可调度性空间平移间歇性能源的出力,平滑广义负荷曲线,平抑波动。建模引入风光蓄多种能源出力最大和广义负荷波动最小的多目标函数,并运用改进的粒子群算法求解。算例分析结果表明:该策略不仅能起到提高间歇性能源的利用率和削峰填谷的效果,还可以减少火电机组启停次数,降低火电经济成本。

关 键 词:间歇性能源  波动性  广义负荷  调度策略  多能互补

Abstract:In order to solve the problems in generation planning and scheduling of power grid brought by the uncer -tainty and volatility of large-scale intermittent energy , in view of the strong volatility of wind generation as well as pho-tovoltaic power generation and grid load , an economical scheduling strategy based on integration of wind , photovolta-ic, water and thermal power has been proposed .The generalized load is defined and the flexible scheduling of pumped storage is used to shift the output space of intermittent energy to smooth the generalized load curves and fluctuation in power .The objective functions that the output of the integration made up of wind , PV and water are the maximum and the fluctuation of generalized load is the minimum which are introduced into the process of modeling , and the im-proved PSO algorithm is used to solve the problem .Through comparison and analysis of simulation results , the pro-posed strategy can not only increase the efficiency of intermittent energy and realize the function of peak load shifting , but also decrease the startup and shutdown of thermal units to reduce the thermal economical costs .
Keywords:intermittent energy  volatility  generalized load  scheduling strategy  energy complementary
