Abstract. In this paper, the modular design is adopted to study the control strategy of photovoltaic system, energy storage system and flexible DC system, so as to achieve the design and control strategy research of the whole system of "photovoltaic + energy storage + DC + flexible DC". This realizes the flexibility and diversity of networking.
By 2030, as much as 80% of electricity could flow through power electronic devices. One type of power electronic device that is particularly important for solar energy integration is the inverter. Inverters convert DC electricity, which is what a solar panel generates, to AC electricity, which the electrical grid uses.
different energy storage features, like specific energy and power, price, number of cycles, expected lifetime, etc. Basic requirements for the connection of production and load facilities to the transmission network are described, as well as challenges regarding energy storage transmission grid integration.

An inverter is one of the most important pieces of equipment in a solar energy system. It''s a device that converts direct current (DC) electricity, which is what a solar panel generates, to alternating current (AC) electricity, which the electrical grid uses. In DC, electricity is maintained at constant voltage in one direction.
