The invention discloses a micro-grid in-situ feedback control method considering frequency recovery and voltage adjustment. The micro-grid in-situ feedback control method comprises the following steps of: S1, analyzing an unbalanced power range based on load frequency voltage change characteristics; S2, calculating the active power regulation capability after isolated grid stable operation; S3, establishing an in-situ feedback construction strategy considering frequency recovery and voltage adjustment; and S4, establishing an in-situ feedback construction strategy considering reactive power equalization. According to the micro-grid in-situ feedback control method, an active power unbalance range which does not cause high-low voltage and high-low frequency protection actions can be deduced according to voltage characteristics of a load, the micro-grid in-situ feedback control method for realizing frequency recovery, voltage adjustment and reactive power equalization is provided, and in-situ calculation of a feedback profit value is realized.
Description
technical field [0001] The invention relates to the technical field of reinforcement learning on-site feedback construction, in particular to a micro-grid on-site feedback control method taking into account frequency recovery and voltage adjustment. Background technique [0002] In MAS, reinforcement learning (RL) is the main method of current research. Multi-agent coordination is mainly based on the learning ability of agents in a distributed environment. Reinforcement learning is an online learning method, which adopts a process of "trial and error-modification" similar to that often existing in human thinking, with the help of feedback information and appropriate algorithms to strengthen good behaviors and weaken bad behaviors, the convergence is Optimal behavior, suitable for problems in which the learner has little knowledge of the environment, or in a dynamic environment. Unlike supervised learning technology, which uses positive and negative examples to tell which b...
