【摘要】：针对含户用光伏系统的社区能源网络有功调配需求,提出一种前推回代优化算法。该方法将光伏发电单元、储能单元与公共连接点(point of common coupling,PCC)整合成参数时变的虚拟网络模型,以"约束条件逐层回代,优化目标逐层前推"的优化方式,求解社区能源网络多目标组合优化问题。在此基础上,依托社区能源网络示范工程,开发能量管理平台对前述算法进行验证。测试结果证明,前推回代优化算法可以根据设备的工作状态,智能调整变量区间,重构优化算法,实现社区能源网络有功统一调配,并在充分考虑储能设备生命周期内剩余工作能力的条件下,实现社区能源网络光伏利用率最大化、储能利用率最大化、PCC有功功率波动最小化的组合优化目标。
[Abstract]:According to the demand of active power allocation in the community energy network with household photovoltaic system, a forward push-back optimization algorithm is proposed. In this method, photovoltaic power generation unit, energy storage unit and common connection point (point of common coupling,PCC) are integrated into a virtual network model with time-varying parameters, and the optimization method is "the constraint condition is replaced layer by layer, the target is pushed forward layer by layer". To solve the multi-objective combinatorial optimization problem of community energy network. On this basis, based on the community energy network demonstration project, the development of energy management platform to verify the above algorithm. The test results show that the forward push-back optimization algorithm can adjust the interval of variables intelligently and reconstruct the optimization algorithm according to the working state of the equipment, so as to realize the unified allocation of active power in community energy network. Under the condition of fully considering the remaining working capacity in the life cycle of energy storage equipment, the combinatorial optimization goal of maximizing the photovoltaic utilization ratio of community energy network and minimizing the fluctuation of active power fluctuation of PCC is realized.
