Example Embodiment

[0032] In order to make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be described in detail below with reference to the accompanying drawings and implementation cases. It should be understood that the specific implementation cases described here are only used to explain the present invention, but not to limit the present invention.

[0033] Such as figure 1 As shown, the microgrid of the present invention includes a multi-agent system of n agents, including distributed power source agents, energy storage system agents, and load agents. Among them, some agents are controlled containment agents, and the rest of the agents track and synchronize in a distributed manner through communication coupling with the containment agent. The restraint-based distributed collaborative control method of microgrid of the present invention is based on the layered control of primary control and secondary control. The present invent...

Abstract

The invention discloses a distributed cooperative control method of a micro power grid on the basis of holdback. The distributed cooperative control method comprises the following steps: step 10), under an islanding mode, when a failure occurs on the micro power grid, an energy storage system agent automatically performs primary control, and an energy storage system runs under a constant-voltage/ constant-frequency control mode, so that the power balance of the micro power grid is maintained; step 20), the micro power grid realizes the secondary control of the system, distributed power supplies are controlled so as to synergistically supply power, the distributed power supplies make up for the power shortage of the system instead of the energy storage system, and the frequency and the voltage are regulated so as to restore to rated values. According to the control method disclosed by the invention, hierarchical control, namely the primary control and the secondary control, is adopted as a basis, so that the control method adopts a distributed control manner, demands and complex communication topology for a central processor are eliminated, only a small part of holdback agents needs to control, and other agents perform tracking synchronization with the holdback agents through communication coupling, so that the number of controller is further decreased.

Description

technical field [0001] The invention belongs to the field of micro-grid operation control, and in particular relates to a pinning-based distributed collaborative control method for a micro-grid. Background technique [0002] With the increasing consumption of traditional energy, distributed generation technology using renewable energy is increasingly widely used in power systems. Microgrid is a distribution subnetwork that includes distributed power generation devices, energy storage devices and local loads, and has certain self-regulation and control capabilities. [0003] Stability control of microgrids has recently received special attention. The control strategy based on the multi-agent system is recognized to play an important role in maintaining the stability of the microgrid, and its control methods include centralized and distributed cooperative control. Among them, centralized control requires a central controller, which needs to process a large amount of data and...
