Research and Application of Rural Integrated Energy System Planning Method Containing Distributed Photovoltaic

In recent years, with the in-depth advancement of the rural revitalization strategy, the vast rural areas have continued to develop in all directions. However, in the field of power and energy, problems such as irrational energy structure, low energy development and production levels, and lagging development of energy system planning and construction still exist. At the same time, the Regional Integrated Energy System (RIES) is increasingly regarded as a key technology for promoting multi-energy complementation and optimizing the energy structure. The abundant solar energy in rural areas of my country has played an important role in RIES. In view of the widespread problem of poor system performance due to the limited grid-connected capacity of distributed photovoltaics(DPV), based on the equipment selection and capacity configuration of conventional RIES planning, this paper proposes a method to consider DPV on-site supply Energy's comprehensive energy system planning method has improved RIES' comprehensive performance in terms of unit energy supply cost, equipment utilization, initial investment and recovery period, and energy onsite supply rate.
