How do you calculate a battery life?

It starts by obtaining the input power of WT, PV, and load, and then calculating the rated power and energy capacity of the battery. Then, it estimates the BESS lifetime using the BESS model and obtains the objective function’s value. If is minimal, the calculation ends.

What is a battery energy storage system (BESS)?

Authors to whom correspondence should be addressed. In standalone microgrids, the Battery Energy Storage System (BESS) is a popular energy storage technology. 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.

Why is a battery energy storage system important?

The battery energy storage systems are used for power demand periods where the DGs are unable to supply the load for only some periods. Hence, BESS is small in size, and costs are reduced accordingly. However, the proper size of a BESS affects its longevity and maintenance or replacement costs.

How can a Bess reduce the cost of a power system?

The optimal capacity of the BESS can significantly reduce the net present value of total operation costs throughout the project by extending its lifetime. When applied to larger power systems, the proposed strategy can further reduce total costs. 1. Introduction

Which batteries are used for energy storage in PV power generation systems?

In Thailand, the batteries widely used for energy storage in PV power generation systems are lead-acid batteries. In order to simulate the operation of the BESS, mathematical models for calculating the charge and discharge parameters and State of Charge (SOC) of the BESS are required.
