Electrical Energy Storage for Buildings

Abstract

There are numerous benefits associated with the addition of electrical energy storage (EES) systems in buildings. It can increase the renewable energy penetration in building, improve power supply grid, and stabilize the building's electrical energy system. This chapter discusses the utilization of EES in built environment, which accounts for an integral share of global electricity end use and CO 2 emissions. In this chapter, the role of EES in building electricity system has been first examined. Several different renewable energy technologies are then reviewed. In particular, two popular and feasible energy storage technologies, i.e., battery and pumped hydro storage, are highlighted. Furthermore, a case study was conducted for a residence house in Shanghai, demonstrating that the grid connected solar photovoltaic system with battery storage performs better than
