考虑电压约束的社区储能系统网络感知需求侧管理框架

Network-Aware Demand-side Management Framework with A Community Energy Storage System Considering Voltage Constraints

摘要:

本文研究了将社区储能(CES)系统与屋顶光伏(PV)发电相结合的可行性,以实现对社区的需求侧管理,同时保持配电网电压在允许的范围内。为此,我们在CES供应商和屋顶光伏系统用户之间开发了一个分散的能源交易系统。通过利用径向配电网络的线性化分支流模型,开发了电压约束的领导者-追随者Stackelberg博弈,其中CES供应商通过与CES系统和电网进行能量交易来最大化收入,并且用户最小化他们的个人能量成本。Stackelberg博弈有一个唯一的均衡,在这个均衡中,CES供应商的收入最大化,用户的能源成本最小化。一个案例研究,与现实的光伏发电和需求数据,证实了能源交易系统可以降低峰值能源需求,防止网络电压波动,同时提供经济利益的用户和CES供应商。此外,模拟强调,与集中式系统相比,分散式能源交易系统为储能容量较小的用户提供了更大的经济效益。

英文摘要:

This paper studies the feasibility of integrating a community energy storage (CES) system with rooftop photovoltaic (PV) power generation for demand-side management of a neighbourhood while maintaining the distribution network voltages within allowed limits. To this end, we develop a decentralized energy trading system between a CES provider and users with rooftop PV systems. By leveraging a linearized branch flow model for radial distribution networks, a voltage-constrained leader-follower Stackelberg game is developed wherein the CES provider maximizes revenue and the users minimize their personal energy costs by trading energy with the CES system and the grid. The Stackelberg game has a unique equilibrium at which the CES provider maximizes revenue and the users minimize energy costs at a unique Nash equilibrium. A case study, with realistic PV power generation and demand data, confirms that the energy trading system can reduce peak energy demand and prevent network voltage excursions, while delivering financial benefits to the users and the CES provider. Further, simulations highlight that, in comparison with a centralized system, the decentralized energy trading system provides greater economic benefits to the users with less energy storage capacity.
