Abstract

The invention discloses a slide control method for the power fluctuation of a microgrid interconnection line. The slide control method comprises the steps of: structuring a power generation plan based on the output of the microgrid interconnection line according to the permeation rate of renewable energy sources, the power curve of temperature-controlled household equipment and the load curve of uncontrollable household equipment; acquiring the power of the renewable energy sources, the load and indoor temperature of non-response type household equipment, and the on-off state and rated power of the temperature-controlled household equipment in real time, working out a target value of aggregated load control response of the temperature-controlled household equipment and establishing a functional relation reflecting the state between the controllable variable of the operation state of a microgrid system and the temperature-controlled household equipment according to the power generation plane based on the output of the microgrid interconnection line, and acquiring the on-off state sequence control signal of the temperature-controlled household equipment for a next step; issuing an on-off state control instruction of the temperature-controlled household equipment by means of the on-off state sequence control signal; and acquiring the actual value of the aggregated load response of the temperature-controlled household equipment based on an equivalent thermodynamics parameter model of the temperature-controlled household equipment, thereby reducing the construction cost of a microgrid.

Description

technical field [0001] The invention relates to the field of microgrid systems for distributed power generation in electric power systems, and in particular to a method for smoothing power fluctuations of tie lines of microgrids. Background technique [0002] Microgrid refers to a microgrid formed by organizing scattered small power generation units (distributed power sources), energy storage devices, and local loads in a certain area. There may be renewable energy sources (such as wind power and photovoltaics) in the microgrid, and the output of these power sources has the characteristics of intermittent, random and uncertain. It is a current hot research issue to effectively overcome the power fluctuation between the microgrid and the conventional distribution network tie line caused by the renewable energy generation system in the microgrid, and then reduce the impact of the microgrid on the distribution system. The fluctuation characteristics of the output of renewable ...
