摘要
主动配电网为高渗透率分布式可再生能源接入提供了有效途径。针对风能等可再生能源所固有的间歇性、波动性与随机性引起的功率波动问题,在配电网中引入储能系统作为可控负荷,建立包含风能与储能系统的主动配电网调度模型,该模型以储能系统的出力为变量;分别以平滑混合毛功率和混合净功率为目标,有效避免可再生能源接入对配电网造成的冲击。提出改进萤火虫算法求解主动配电网优化调度问题。仿真算例验证了所提模型与算法的有效性。
Active distribution network provides an effective way for the access of distribution renewable energy with high penetration. Aiming at the power fluctuation problem caused by the inherent intermittence,fluctuation,and randomness of wind energy,ESS(Energy Storage System) is introduced into distribution network as a controllable load,and a dispatch model of distribution network with wind energy and ESS is built,which takes the ESS output as its variable. Smoothing the hybrid gross output and hybrid net output are respectively taken as the objectives to effectively avoid the impact of renewable energy access on distribution network. An improved firefly algorithm is proposed to solve the optimal dispatch problem of active distribution network. Simulation example verifies the effectiveness of the proposed model and algorithm.
