论文摘要
在本文中，屋顶光伏（PV）功率与社区储能（CES）系统的整合可以减少能源成本和分配网络（DN）损失的程度。为此，比较了三个能源交易系统（ETS）；首先，PV用户除了网格之外，PV用户将能源与CES系统交换，其次是PV用户仅与CES系统交换能量的ET，而第三，PV用户只有PV用户仅将能量与网格交换。开发了一个多目标优化框架，再加上线性分配网络功率流模型，以研究能源成本和网络功率损失减少之间的权衡，同时满足DN电压和当前流量限制。具有实际的能源需求和PV功率数据的仿真强调，可以使用户与CES系统之间的能源交换可以在DN功率损耗和降低能源成本之间更好地取舍。此外，模拟表明，与没有CES系统的ET相比，所有三个ETS均能降低近85％的DN能量损失，收入显着增加。
In this paper, the extent to which the integration of rooftop photovoltaic (PV) power with a community energy storage (CES) system can reduce energy cost and distribution network (DN) loss is explored. To this end, three energy trading systems (ETSs) are compared; first, an ETS where PV users exchange energy with the CES system in addition to the grid, second, an ETS where PV users merely exchange energy with the CES system, and third, an ETS where PV users only exchange energy with the grid. A multi-objective optimization framework, combined with a linear distribution network power flow model, is developed to study the trade-off between the energy cost and network power loss reductions while satisfying the DN voltage and current flow limits. Simulations, with real energy demand and PV power data, highlight that enabling the energy exchange between the users and the CES system can give a better trade-off between the DN power loss and energy cost reductions. Further, simulations demonstrate that all three ETSs deliver nearly 85% DN energy loss reduction with significantly increased revenues compared to an ETS without a CES system.
