Integrated energy system planning technology and case verification on commercial buildings

As the development of the economy, the energy demand of users has changed from a single demand for electric energy to a multiple demand for electric energy, heat energy and cold energy. At the same time, photovoltaic power generation is becoming more and more popular in energy supply system. With the aim to meet multiple types of energy demands from users, an integrated energy system planning method was proposed in this article. It met the economic energy demand of users through the optimized configuration of various energy supply equipments and the optimization of the operation mode. Finally, we took commercial buildings as the planning object to do the verification study. The energy supply equipments included six elements, such as heat pump unit, photovoltaic power generation system, and electrochemical energy storage unit. The effectiveness of the integrated energy planning method was tested through this planning case.
