Performance Analysis For Stability Enhancement of Hybrid Power System Using Heuristic Techniques

Abstract

The rapid change in energy production and consumer demand hybrid energy systems have been newlineintroduced for last few years. In conventional times there were a lot of challenges such as energy cost newlineand maintenance cost in addition with less number of energy sources which introduced towards new newlineresearch technologies for generation of electricity. By using single energy source there is problem of newlinecontinuous production of electricity due to environmental conditions. Fossil fuels also introduce gas newlineemission problem and less efficient power. Many researchers have explored towards renewable newlineenergy sources for increasing the efficiency with reduction of cost of energy. In remote areas there newlinewas problem of providing continuous power supply as per load demand. Conventional energy newlinesources may have high maintenance cost and consist of more gas emissions. Hence renewable energy newlinesources have been introduced. newlineBy employing these renewable energy sources there may be possibility of low reliable power due to newlineclimatic changes so advanced research has been done in the field of solar, wind, hydro etc to solve newlinethe problem of energy demand. An extensive research has done for improving efficiency by using newlinenumerous maximum power point tracking approaches. Investigation of different types of controlling newlinemethods in renewable energy system represents about hybrid controlling technique which is most newlineefficient and reliable as compared to other controlling method. newlineSo hybridization of various renewable energy system means interfacing of two or more energy newlinesources provides continuous energy supply. Due to variation in weather conditions energy varies and newlineintroduces instability of system parameters which results in poor power quality. Sometimes it may newlineincrease cost due to combining features of two or more energy system as per load demand and power newlinesupply. Such hybrid energy system consists of converters for the comparison of energ newline
