Abstract

In this paper, a village energy system is coupled with the wide-area energy network based on the energy hub concept. The village is modeled as an isolated energy hub while it could interact with the energy sub-networks including the electrical, and natural gas through the market. The energy demand of village is supplied with renewable resources such as photovoltaic (PV) system and other generation such as combined heat and power (CHP) technologies. The CHP unit is modeled by the part-load performance. In addition, the battery energy storage is presented beside the PV system to damp the intermittent generation of PV and to be utilized in the high prices of the market. The optimal operation problem is solved to maximize the profit from the energy hub operator point of view. The optimization problem is solved with the teaching-learning based optimization (TLBO) method. The results show that the proper interaction of the village energy system with the upstream sub-networks is so affordable for the system operator to increase the profit, in a way that the maximum benefit of village energy system is reached to 3.6456$.

考虑可再生资源和电池储能的村庄能源系统优化运行

本文基于能源枢纽的概念，将村庄能源系统与广域能源网络进行耦合。该村庄被建模为一个孤立的能源中心，同时它可以通过市场与包括电力和天然气在内的能源子网络进行交互。村庄的能源需求通过可再生资源如光伏(PV)系统和其他发电如热电联产(CHP)技术来满足。采用部分负荷特性对热电联产机组进行了建模。另外，在光伏系统的旁边提出了电池储能，以抑制光伏的间歇性发电，并在高价格的市场中加以利用。从能源枢纽运营商的角度出发，解决了能源枢纽的最优运行问题，以实现利润最大化。采用基于教与学的优化方法求解优化问题。结果表明，村落能源系统与上游子网络的适当互动，使系统运营商能够承受得起，从而增加利润，村落能源系统的最大效益可达3.6456美元。
