Abstract

The invention is suitable for the technical field of microgrid control, and provides a virtual synchronous generator control method and device and terminal equipment. The method comprises the steps ofobtaining the performance parameters of each virtual synchronous generator unit in a microgrid system, and calculating the total virtual inertia of the microgrid system and the weight corresponding to each performance index according to the performance parameters, calculating a positive ideal solution and a negative ideal solution according to each performance parameter and the weight, and further calculating a comprehensive evaluation index of each virtual synchronous generator unit, and finally, calculating the virtual inertia of each virtual synchronous generator unit according to the comprehensive evaluation index and the total virtual inertia. Through the virtual synchronous generator control method provided by the embodiment of the invention, the corresponding virtual inertia can bereasonably determined for each virtual synchronous generator under the condition that the performance parameters of each virtual synchronous generator are different, and the operation stability of the microgrid system is improved.

Description

Technical field [0001] The invention belongs to the technical field of microgrid control, and in particular relates to a virtual synchronous generator control method, device and terminal equipment. Background technique [0002] The installed scale of photovoltaic power generation systems in the power grid continues to increase, but the photovoltaic power generation system itself does not have inertia. Therefore, when the photovoltaic power generation system is connected to the power grid through a power electronic converter, the total inertial capacity of the entire system will decrease. For this problem, virtual synchronous generator control is used to achieve friendly grid connection when photovoltaic and energy storage devices are operating in coordination. [0003] The optical storage unit under the control of the virtual synchronous generator will be restricted by the relevant performance parameters of the system during its operation. Factors such as the state of charge of the...
