Embodiment Construction
[0038] like figure 1 Shown is a schematic diagram of the method flow of the method of the present invention: the micro-grid energy dispatching method that considers the interaction of optical storage, charging and multi-subjects provided by the present invention includes the following steps:
[0039] S1. Obtain the real-time operating parameters of the target power grid;
[0040] S2. The target grid issues load adjustment instructions to the subordinate microgrids according to the current operating status; in actual operation, the load adjustment instructions require the microgrids to limit power consumption most of the time, that is, require the microgrids to reduce their own loads , limit self electricity consumption; Therefore the inventive method also only considers this situation;
[0041] S3. The microgrid issues load regulation sub-commands to subordinate entities according to the received load regulation instructions;
[0042] S4. The main body with excess electric e...

The invention discloses a micro-grid energy scheduling method considering optical storage and charging multi-agent interaction. The method comprises the following steps: acquiring real-time operation parameters of a target power grid; the target power grid issuing a load adjusting instruction to a subordinate micro-power grid; the micro-grid issuing a load regulation sub-instruction to each subordinate main body; the main body with the redundant electric energy in the micro-grid determining the contract electricity price of the redundant electric energy; other main bodies in the micro-grid deciding own power utilization strategies on the premise of meeting the load regulation sub-instructions of the micro-grid; and completing energy scheduling of the micro-grid according to the power utilization strategy. According to the method, consumption of renewable energy sources in the micro-grid is finally realized, the efficiency of each main body in the micro-grid is improved, the cost is reduced, the load regulation capability of the micro-grid in the target power grid is improved, the regulation and control difficulty of the power grid is reduced, energy flow in the micro-grid is also promoted, the new energy consumption in the micro-grid is improved, the reliability is higher, and the practicability is better.
