Embodiment Construction

[0092] In order to make the objectives, technical solutions and advantages of the present invention clearer and clearer, the present invention will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention.

[0093] The structure of the island intelligent distribution network model is as follows figure 1 As shown, it contains 1 distribution network, 3 microgrids, 19 adjustable units, with a total regulated power of 2760kW, and non-adjustable units as load disturbance output. Moreover, each adjustable unit has a corresponding agent, and the connection weight between agents b ij Choose as 1. Step disturbance (final amplitude: 1000; assessment period: 86400s), pulse disturbance (amplitude: 1000; assessment period: 86400s; period: 4000s; width: 50% of the period) and random white noise (noise power: 1...

Abstract

The intelligent power generation control method of a virtual wolf cluster control strategy under an island intelligent power distribution network comprises steps of determining a state discrete set S,determining a combined motion discrete set A, obtaining value function errors Rhok,Mk, updating all Q function tables and time a tunnel matrix e (sk,ak) which correspond to all state-motions (s,a), updating Q values and updating a mixed strategy pi(s<k>, a<k>) under the current state s, updating a tunnel element e (s<k>, a<k>), selecting a variable learning rate phi, and updating a decision change rate delta (s<k>, a<k>) and a decision space estimation slope delta2(sk, ak) according to a function, outputting a total power reference value delta P sigma and using a consistency algorithm and calculating unit regulation power delta PGi. The intelligent power generation control method of the virtual wolf cluster control strategy under the island intelligent power distribution can solve multi-solution problem produced by a large scale surge of multiple intelligent objects, can solve a random disturbance problem caused by large scale access of new energy and realizes coordinated control andoptimization of a multi-layer distributed control system.

Description

Technical field [0001] The invention relates to an intelligent power generation control technology of a power system, in particular to an intelligent power generation control method of a virtual wolves control strategy under an island intelligent power distribution network. Background technique [0002] With the rapid development of smart grids, the continuous expansion of installed capacity, and the continuous access of new energy and distributed energy sources, the traditional centralized automatic generation control (AGC) mode is difficult to meet the development and operating conditions of the power grid. Distributed AGC control mode It is imperative. [0003] From the perspective of distributed energy utilization, due to the limitations of grid structure, power plant capacity and unit regulation speed, different types of power plant capacity and unit regulation speed limitations, different types of power plants have huge differences in power allocation and utilization. The po...
