摘要:
针对分布式风电、光伏并网对电网调度运行的影响,利用光热电站(concentrating solar power plant,CSP)出力可调的特点,联合储能电池构建包含风电、光伏、光热及储能电池的多能源虚拟电厂(virtual power plant,VPP)。根据光热及储能电池特性,基于分时电价制定运行策略,以各时段净收益最大为目标,建立虚拟电厂两阶段优化调度模型。在日前调度中,综合风光预测出力,考虑分时电价和光照因素,优化光热出力,制定申报出力计划;在实时调度中,光热通过储热装置充放热对风光出力偏差进行修正,储能电池辅助光热对偏差进行调节,并采用自适应粒子群算法优化各单元出力。最后,通过仿真验证所建模型合理性及运行策略可行性。结果表明采用光热和储能电池联合调节,可有效降低虚拟电厂实时出力跟踪申报出力偏差,提高经济效益。
