Abstract: This paper proposed an energy system for the integration of renewable energy with energy storage in a frigid plateau region. The system was intended for an isolated residential community with heating and power demands, which includes wind, photovoltaic, and hydroelectric power generation, trough solar collector, heat storage unit, electrical energy storage unit and an integrated control unit for achieving a high effciency in the utilization of renewable energy. An optimization method based on the genetic algorithm was established for the proposed system, aimed at fnding a confguration with optimal economics. Besides, a real-time energy management strategy, which took into account the performances of components, was proposed to ensure an effective operation of the system. A case study was then conducted to minimize the annualized cost of the system. The results showed the feasibility of the energy management strategy.

Key words: frigid plateau region, renewable energy, energy storage, optimal sizing, energy management
