Abstract

The main objective of this paper is the cost optimization of Hybrid Energy System (HES) - a combination of a solar Photovoltaic (PV), Wind Turbine (WT), battery and a Diesel Generator (DG). In recent years, HES has become one of the most significant and promising system, which requires safer means of maintaining the system’s security, stability and reliability and with a large number of distributed generation access, it cannot be ignored. These have become common in remote space, power generation applications as a result of advancements in renewable energy technologies. The main aim is to cover the load demand under varying weather conditions and to control the power delivered by a 100 KW HES and also overall Power Management Strategy (PMS) is designed for HES to manage the power flows among the different energy sources and the storage unit in the system. The control of internal powers and PMS should be implemented to satisfy the stand-alone requirements while maximizing the benefit of Renewable Energy Source (RES) and optimizing the operation of each storage unit. HOMER is used to evaluate the optimal sizing of the components in HES and reliability is also fulfilled at the same time.  In this, the electrification costs like capital, replacement, operation and maintenance cost and fuel cost are considered for optimal designing.
