Abstract

The invention discloses a community-level microgrid economic operation modeling and solving method in consideration of temperature control equipment. Through research on the temperature adjustment features of the temperature control equipment, factors influencing the microgrid economic operation are analyzed, the microgrid with the temperature control equipment serves as a research object, a microgrid optimal economic operation model inconsideration of the temperature adjustment features of the temperature control equipment is built, and the total cost such as operation cost, fuel cost, energy storage loss and wind curtailment punishment cost is considered to be minimum to serve as the target. The model is solved through a hybrid particle swarm optimization algorithm, and factors considered by the built microgrid economic operation model are more thorough, the algorithm is simple and is convenient to be learnt and used by an engineering person, the universality is good, and the method can be widely applied to microgrid economic operation analysis.

Description

technical field [0001] The invention relates to the economical operation technology of electric power system, in particular to a community-level micro-grid economical operation modeling and its solution method taking into account temperature control equipment, and belongs to the field of economical dispatching of electric power system. Background technique [0002] New energy sources such as solar energy and wind energy have the characteristics of randomness and intermittency. After being connected to the grid, their operation and scheduling are more difficult. The emergence of microgrid provides an effective means for the comprehensive utilization of renewable energy. For microgrids, the important role of economically optimized operation is to rationally distribute the output of micropower sources and improve the acceptance capacity of new energy sources. With the access of various forms of energy and the consumption demand of various forms of energy, more and more microgr...
