About this Research Topic
Currently there are still about 1.2 billion people in the word without grid electricity, most of them living in remote areas, such as islands, mountain areas and isolated villages. Grid extension to such remote communities is both uneconomical and technically difficult owing to dispersed population or rugged terrain. Fortunately, those remote areas are usually rich in renewable energy resources, such as solar, wind, biomass, and hydro energy, thus exploring the locally available renewable energy resources is the best possible option to meet the energy requirement.
Depending on the site conditions, single technology or hybrid technologies would be selected in stand-alone mode for remote area power supply. However, renewable energy resources are highly site-specific and intermittent in nature. Therefore, as demand increases in stand-alone mode, single technology based system are associated with high system cost and low reliability, and thus the concept of hybrid renewable energy system has been introduced for power generation in stand-alone applications to deal with such limitations of single technology based system. In some cases, the conventional diesel generator can be added as well, since a small diesel generator can cover the peak load and supply power for poor weather conditions over a long period of time. The introduction of a diesel generator can improve power supply reliability and significantly reduce both storage and renewable energy capacity, hence reducing system cost, whilst an optimal combination of renewable energy and storage can limit diesel fuel consumption of the generator.
In recent years, stand-alone renewable energy power generation systems have been becoming the research focus in this field, and some attempts have been made to develop the hybrid energy technologies for remote area power supply. Therefore, there is a need to understand the current status and future development with respect to renewable energy power generation technologies (with or without diesel generator), energy storage technologies, system configuration, system modelling & simulation, sizing & optimization techniques, operation & management, performance evaluation. This Research Topic aims to call for papers on technical, social, financial and environmental issues of utilizing standalone renewable energy microgrid system for power supply in remote areas.
