Optimisation of hybrid renewable energy system using iterative filter selection approach

Abstract

This study presents a hybrid renewable energy system that yields minimum total project cost and maximum reliability. The system is in modular configuration consisting of photovoltaic (PV) array, wind turbine, battery storage, AC load and a dump load. Also, the minimisation of unutilised surplus power is taken into consideration as one of the design objectives. In this study, a new technique named iterative filter selection approach is used in designing the hybrid PV-wind turbine-battery system to obtain the best acceptable solution while considering all the design objectives. The system is then justified by comparing with iterative-Pareto-fuzzy and particle swarm optimisation techniques. The technique is found to be superior in terms of total project cost with satisfaction to the load demand. The method is simulated using MATLAB and the results are presented in the study with proper discussion.

Investigation on the Development of a Sliding Mode Controller for Constant Power Loads in Microgrids

“…In this paper, a sliding mode controller (SMC) has been selected over a PID controller due to its considerably better performance [39][40][41][42][43][44][45]. In Figure 11, performance comparisons between PID (blue colored) and SMC (red colored) have been shown in the case of: (a) real axis output voltage and (b) reactive axis output voltage for nonlinear system application.…”

Grid-Tied Photovoltaic and Battery Storage Systems with Malaysian Electricity Tariff—A Review on Maximum Demand Shaving

“…Geem and Yoon [70] proposed an efficient harmony search algorithm for charge scheduling of an energy storage system (ESS) with renewable power generators, under time-of-use pricing and demand charge policy. The summary of the reviewed paper on Table 3 shows the techniques used for peak shaving, load leveling and load shifting using solar PV-battery system [71]. Table 3.…”

An Original Transformer and Switched-Capacitor (T & SC)-Based Extension for DC-DC Boost Converter for High-Voltage/Low-Current Renewable Energy Applications: Hardware Implementation of a New T & SC Boost Converter

“…In recent years the importance of using renewable energies has grown significantly due to the fact that the usage of fossil fuels such as oil, coal, and gas results in environmental pollution and serious greenhouse effects which have a huge influence on the world [1,2]. The demands for energy and power converters have been increasing for the last several decades, due to the greater industrialization, rising population and increased living standards of society [3][4][5][6][7][8][9].…”
