“…In 2013, 3 single-phase 25 kVA/25 kWh CES units have been installed on LV network at Chalvey, Slough in England as part of SSE Zero Carbon Homes project. Project that includes 65 kW PV generation and several electric vehicle units has successfully achieved 34% reduction in peak load and prevented the reverse power flow [12]. In addition to this, dynamic analysis conducted for a system with clustered proliferation of PV-Distributed Generation and Plug-in Electric Vehicle (PEV) in a feeder branch presented in [13] reveals that CES deployment can provide smooth demand power, mitigate feeder voltage fluctuation thus reduce transformer load tap changer operation.…”

Community Energy Storage (CES) has been known as a new generation of energy storage that is a crucial element in smart grid. Its location at the edge of the grid and close to customers offers great benefits compare to energy storage located at substation in terms of smoothening the impacts of intermittent Renewable Energy (RE) resources and diversity of Electric Vehicle (EV) operational characteristics. Power utilities found that CES deployment along with reliable planning and control system can become a smart solution in providing sustainable energy and open new business opportunity. However, despite the benefits, CES deployment in distribution system with the integration of PV and EV may face several challenges. This paper provides an overview of CES, covering technology, prospect, challenges and opportunity in obtaining a reliable smart distribution system with optimal cost. In addition, preliminary simulation works are presented to show the effectiveness of CES in reducing power loss and improve voltage profile compare to a central battery located at substation.

“…As mentioned in the previous subsection, the first project of CES has been developed in 2009 by AEP utility as part of AEP Ohio's gridSMART demonstration project, which includes the integration of community renewable energy and plug-in electric vehicle. Operation of CES units in AEP Ohio gridSMART projects is controlled by distributed energy management (DEM) controller consists of three layers of intelligent control situated at distribution substation [11], [17] several electric vehicle units has successfully achieved 34% reduction in peak load and prevented the reverse power flow [25]. In addition to this, dynamic analysis conducted for a system with clustered proliferation of PV-DG and plug-in electric vehicle (PEV) in a feeder branch presented in [26] reveals that CES deployment can provide smooth demand power, mitigate feeder voltage fluctuation thus reduce transformer load tap changer operation.…”

Energy storage (ES) system has become an inevitable element in smart distribution network (DN) due to massive deployment of renewable energy resources (RERs). ES is capable of solving a number of operational problems in distribution network due to intermittent characteristic of the RERs while providing numerous other benefits such as ancillary services, peak reduction, reliability improvement etc. Among various type of RERs, community level distributed photovoltaic (PV) is the fastest-growing power generation system due to its technological advancement; declining price and better fit into consumer area. Thus, impact of intermittent PV output power is more severe in community level where the consumption is happening. Hence, the idea of bringing ES close to the source of the problem has led to the development of concept called community energy storage (CES). Most available studies claimed that the deployment of CES is more effective in alleviating the impact of high PV penetration while offering more benefits than the centrally located substation storage if properly planned and effectively controlled. However, comprehensive review found that very scant analytical evidences were shown to prove the statement. Besides, currently CES allocation is determined based on maximizing specific benefit while neglecting others benefits of its deployment. Very scarce previous works provided a complete allocation
