An autonomous micro-generation site using alternative/autonomous sources of electric energy

Abstract

Introduction: the article deals with development and implementation of an autonomous, scalable and flexible-capacity micro-generation site representing a combination of various alternative sources of electric energy (up to 30 kW). The co-authors offer a solution for an autonomous micro-generation site: a prototype of a modular platform for a hybrid power plant (MPHP), which enables the use of solar and wind energies, capacitors, as well as an autonomous standby power supply unit having an internal combustion engine. The basic idea underlying the concept of a modular platform and the module combination method are substantiated. Power supply patterns that comprise MPHP are provided. Testing results, as well as the economic efficiency of a system operating in a decentralized energy supply environment are presented in the article.Methods: the study is based on the analysis of strengths, weaknesses and features of existing energy systems using alternative/autonomous sources of electric energy with a view to the extension of capabilities and capacity by means of connecting new generating sources.Findings and discussion: the results of development of an autonomous micro-generation site are presented; a prototype of a modular platform for a hybrid power plant (MPHP) is manufactured.Conclusion: the modular platform of a hybrid power plant enables to combine different types of electric energy sources and retain effective control over operating modes, thus improving the energy supply reliability and saving organic fuel consumed for the generation of 1 kWh of electricity.
