Abstract

The invention discloses a double-layer optimization method for an alternating current and direct current hybrid microgrid based on demand side response. The method comprises the following steps: basedon the stimulated demand side response, through the adjustment of shiftable load, enabling a load curve to get close to a renewable energy source contributed change curve, using the maximum of renewable energy source consumption rate as a target to establish an upper target function of the alternating current and direct current hybrid microgrid; taking the demand side response based on price intoaccount and also taking the demand side response based on stimulation into account, establishing a lower target function taking minimum operating cost of the alternating current and direct current hybrid microgrid as a target; complying with operation constraints, and establishing a double-layer optimized mathematical model of the alternating current and direct current hybrid microgrid; improvinga culture genetic algorithm, and solving the double-layer optimized mathematical model of the alternating current and direct current hybrid microgrid. According to the method, the maximum of renewable energy source consumption rate is taken as the upper target function, the minimum operating cost of the alternating current and direct current hybrid microgrid is taken as the lower target function,the double-layer optimized mathematical model of the alternating current and direct current hybrid microgrid can realize efficient utilization of renewable energy sources, and the method is beneficial for economic operation of the alternating current and direct current hybrid microgrid.

Description

technical field [0001] The invention relates to an optimization method for an AC-DC hybrid microgrid. In particular, it relates to a two-layer optimization method for AC / DC hybrid microgrid based on demand side response. Background technique [0002] With the increasingly prominent energy crisis, the development and utilization of renewable energy is imminent. Distributed power sources such as wind power generation and photovoltaic power generation can realize efficient utilization of new energy, which is a hot research topic at present. However, because its output is limited by nature and has significant randomness and volatility, it is also a current research difficulty to consider the uncertainty of scenery. The microgrid integrates distributed power sources, loads, energy storage and power electronic devices, etc., and can realize efficient management and utilization of distributed power sources through coordinated control technology. With the diversification of load ...
