Programming of Energy Storage System in an Island Microgrid with Photovoltaic and Fuel Cell

Photovoltaic (PV) systems in island microgrids (MGs) are becoming increasingly attractive as a means of energy generation, due to new developments in technologies, environmental concerns, and transmission congestion management. Usually, the energy storage system (ESS) is used to store the excess power generated during off-peak hours, and to return it to the system when power from PV is not enough for the system, or generation is more expensive. A real-time dynamic programming algorithm for energy storage in a PV/battery system, based on the battery charge and discharge characteristics, and current and temperature dependence of the capacity of the battery, is presented in this paper. The work aims to extend existing battery- aware programming techniques. It differs from previous works, as it takes into consideration many aspects of battery characteristics that were not considered previously. This allows better use of the battery bank and can prolong the battery service time. This paper also builds a simple PV/battery system in an island microgrid. In this paper, fuel cell power plants (FCPPs) are permanently used to operate in island microgrids, and 2 batteries are used as reserves for charge and discharge in various hours. doi:10.14456/WJST.2015.28
