Development of a comprehensive energy management for microgrid

Abstract

The thesis focuses on integrated energy management strategies for microgrid systems, and constructs an off-grid energy system that includes photovoltaic, wind, heat pump, boiler and energy storage. The energy systems in Tianjin and Finland are modelled and optimised using HOMER Pro software, taking into account the differences in load characteristics and renewable energy availability under different climatic conditions. Through the comparative analysis of system configuration, operation mode and economic performance, the paths to achieve stable energy supply and sustainable development in different regions are evaluated. The study shows that microgrids have good regional adaptability and expandability, and provide a reference for the optimisation of energy systems in different regions.
