Abstract
The objective of this work is to develop a power management system that will control the power flow of an integrated renewable energy system with the focus on solar energy and wind energy and dual energy storage systems (batteries are used as the primary energy storage system for short to moderate storage term, whereas hydrogen fuel cell is used as a backup and long-term energy storage). These storage systems are needed to provide high reliability and control systems are necessary for the stable and optimal operation of the whole system. An Intelligent Power Management System (IPMS) is developed to handle various changes in power supply and power demand by managing erratic power and provide suitable control algorithm for the whole system. In order to test and validate the proposed IPMS model, simulations were conducted under various power supply and power demand using power system modeled in HOMER environment. The performed simulations confirm the ability of the IPMS to satisfy the load at all times using solar and wind power (which are unsteady renewables), through the support of batteries and hydrogen fuel cell without a reduction in the power quality or load supply.
Highlights
Results obtained from designed software module and that gotten from Hybrid Optimization of Multiple Energy Resources (HOMER) setup shows a close agreement between them
The results of the demand met by the integrated renewable energy system (PV/Wind/Battery/Fuel Cell) for three consecutive days are shown in Tables 1–3 and Figures 6–11
The Fuel cell is used to assist the increasing load demand supply and concurrently charge the battery storage when the renewable energy sources are unavailable and the battery storage have reached its minimum state of charge
Summary
The application of renewable energy sources for electricity generation and utilization has seen a huge potential, and a number of studies have been conducted by many researchers on various aspects of renewable energy development and utilization (Anees, 2012; Sen and Bhattacharyya, 2014; AbiolaOgedengbe et al, 2015; Reboredo, 2015; Wesseh and Lin, 2015; Alharthi et al, 2018; Jiang et al, 2018; Mehrpooya et al, 2018; Shoeb and Shafiullah, 2018). In order to maintain the energy sustainability of different energy sources, many Power Management Systems (PMS) are proposed in literature (Behzadi and Niasati, 2015; Mhusa et al, 2015; Onur and Ismail, 2015; Albert Martin et al, 2015; Ranjit, 2016; Ceran et al, 2017; Sassi et al, 2017; Moghaddam et al, 2019). Ranjit (2016) proposed a complete hardware system development, implementation and construction of real-time direct current (DC) integrated renewable energy system (HRES) for solar-wind-battery energy source hybridized with grid network support for optimal system controllability and operation. A Power Management System (PMS) is studied for an integrated PV/Wind/Battery/Fuel Cell System
