Three-tier framework of multi-source coordinated optimization dispatch for active distribution network

合理协同各类并网间歇性能源、储能装置、柔性负荷等可调资源,是实现主动配电网优化调度的有效途径。在设置各类能源调度顺序及分段开关控制方案的前提下,从环境、运行、经济三个层面,构建主动配电网多源协同三层优化调度模型,并运用一种融有蛙跳算法、遗传算法核心思想的改进人群搜索算法求解该模型。仿真结果表明多源协同优化调度可有效提升可再生能源消纳率、平稳负荷波动、降低网络损耗、提高用户体验,由此证明该优化方案的合理性及优越性。

Reasonable coordination of various types of grid-connected intermittent energy,energy storage devices,flexible load and other controllable devices is an effective way to achieve the optimal dispatch of active distribution network.Based on the setting of various energy dispatching order and the control scheme of segment switches,the three-tier framework of multi-source coordinated optimal dispatching model was constructed from three aspects of environment,operation and economy,meanwhile,an improved seeker optimization algorithm mixed with the core idea of frog leaping algorithm and genetic algorithm is adopted to solve it.Finally,simulation results showed that the multi-source coordinated optimal dispatch can effectively improve the accommodation rate of renewable energy,smooth loads fluctuation,reduce network power loss and improve user experience,which verifies the rationality and superiority of the proposed optimization scheme.
