A Review on Recent Optimal Sizing Methodologies and Evaluation Indicators for Hybrid Renewable Energy System

Electricity demand in islands and remote areas is generally supplied by diesel generators or other fossil fuels because they are far from the utility grid. Nevertheless, the research trends nowadays are to reduce the reliance on fossil fuels by working on renewable energy. Renewable energy sources provide numerous benefits to rural and remote areas, including sustainability, environmental tolerance, low pollution, and economic advantages. However, the majority of renewable energy sources are uncontrolled and unpredictable. To address these drawbacks, hybrid systems involving the use of multiple types of renewable energy resources and/or traditional energy resources and/or storage systems have been developed. However, sizing for hybrid renewable energy can be difficult due to a number of factors, such as the sizing of system components and the integration of each component to optimize system performance. As a result, the primary purpose of this work is to conduct a review of the most recent configuration of HRES, techniques to addressing optimization issues, and evaluation indicators of hybrid renewable energy system (HRES).
