Abstract

The invention discloses an optimized operation method for a c co-generation micro-grid. The method comprises the following steps: 1, carrying out modeling on co-generation micro-gridequipment; 2, establishing a wind and light unit output uncertainty model; 3, establishing a user thermal comfort degree and heat supply area thermal inertia model; 4, establishing a demand response model based on a price elasticity matrix; 5, processing the output randomness of the wind and light units in the co-generation micro-grid by using interval linear programming; 6, establishing a co-generation micro-grid optimization scheduling model; and 7, carrying out solving by applying MATLAB in combination with a Gurobi solver. Example results show that the optimization model provided by the invention has good robustness, and the economic cost is reduced and thermoelectric decoupling is realized while the uncertainty is effectively processed.

Description

technical field [0001] The invention belongs to the technical field of electric power systems, and in particular relates to an optimal operation method of a cogeneration microgrid. Background technique [0002] Energy Internet has risen to the status of national strategic development. my country is vigorously promoting energy reform and advocating the improvement of energy utilization. Combined heat and power microgrid can not only realize the cascade utilization of energy, but also improve the utilization rate of energy, which has attracted widespread attention at home and abroad. Traditional combined heat and power microgrid is constrained by the operation mode of "constant power by heat", which limits the operating efficiency of equipment and affects the economy of the system. There are a large number of uncertain factors in the operation of the microgrid, and how to solve the uncertain factors in the system is also a major problem. Therefore, a new technology is needed...
