A novel formulation for the battery energy storage (BES) sizing of a microgrid considering the BES service life and capacity degradation is proposed. The BES service life is decomposed to cycle life and float life. The optimal BES depth of discharge considering the cycle life and performance of the BES is determined.
Nowadays, microgrids (MGs) have received significant attention. In a cost-effective MG, battery energy storage (BES) plays an important role. One of the most important challenges in the MGs is the optimal sizing of the BES that can lead to the MG better performance, more flexible, effective, and efficient than traditional power systems.
Because of renewable energy generation sources such as PV and Wind Turbine (WT), the output power of a microgrid varies greatly, which can reduce the BESS lifetime. Because the BESS has a limited lifespan and is the most expensive component in a microgrid, frequent replacement significantly increases a project’s operating costs.
The power supply and distribution system, charging system, monitoring system, energy storage system, and photovoltaic power generation system are the five essential components of the PV and storage integrated fast charging stations. The battery for energy storage, DC charging piles, and PV comprise its three main components.
Because the BESS has a limited lifespan and is the most expensive component in a microgrid, frequent replacement significantly increases a project’s operating costs. This paper proposes a capacity optimization method as well as a cost analysis that takes the BESS lifetime into account.
The lifetime of the microgrid is 20 years, with a load growth of 2% each year. According to the longitude and latitude of Kythnos island, the renewable resource data can be found from NASA Surface Meteorology and Solar Energy Web site . The monthly average wind speed, solar radiation and temperature are listed in Table 1.
