Research on Key Technology of Photovoltaic-Energy Storage-Charging-Discharging Integrated System based on Electric Energy Metering

With the wide application of new energy generation methods such as photovoltaic power generation and the popularization of electric vehicles, how to integrate and plan the distribution of electric energy resources is the main problem facing the use and consumption of new energy. The PV-energy storage-charging-discharging integrated system aims to optimize resource allocation, and unify the planning and coordination of energy flow among PV power generation, energy storage, charging piles, and power-using equipment. This paper proposes an integrated PV-energy storage-charging-discharging system, analyzes the system structure and the functions of each system part, constructs a system optimization operation model, and finally simulates and analyzes the impact of optimization strategy on the peak and valley values of loads by taking electric vehicle loads as an example.
