The invention discloses a comprehensive energy storage optimization configuration method and system, combined with the architecture of the user-side comprehensive energy system, given the energy demand of the system at each time period and the maximum output of energy production units in the system at each time period; and establishing an energy conversion unit in the system and the physical model of the energy storage unit; establish a comprehensive energy storage optimal configuration model aiming at the minimum load variance, the minimum reduction of renewable energy, and the minimum comprehensive energy storage capacity. The optimal solution of the model is the configuration that each type of energy storage device should configure optimal capacity. It can be applied to user-side integrated energy systems with various specific architectures. Through multi-energy complementarity and coordinated optimization of multi-energy flows, the user-side integrated energy system can fully exploit the potential of user-side integrated energy systems to reduce power grid load peak-valley differences and improve renewable energy consumption capacity. effect. This method can coordinate with electric heating and cooling integrated energy storage to promote peak shaving and valley filling and renewable energy consumption, effectively improving the operation safety and economy of the power system.
Description
technical field [0001] The invention relates to the technical field of comprehensive energy, and discloses a comprehensive energy storage optimization configuration method and system. Background technique [0002] In recent years, the peak-to-valley difference of power grid load in my country has further widened, and the load characteristics of the power grid have deteriorated, which is not conducive to the economic operation of the power system. In addition, the proportion of renewable energy power generation such as wind power and photovoltaic power generation continues to increase. Due to the lack of flexible adjustment capacity of the power system, renewable energy power generation is facing severe consumption problems. [0003] In the face of problems such as widening load peak-valley difference and renewable energy consumption, many studies have sought solutions from the user side, such as rationally configuring electric energy storage in the microgrid, and reducing pe...
