Comprehensive station optimization operation method in multi-station fusion mode

Abstract

The invention discloses a comprehensive station optimization operation method in a multi-station fusion mode. The method comprises the following steps: acquiring operation data of a comprehensive station in the multi-station fusion mode; establishing constraint conditions of the charge state, the charge and discharge power and the power balance of the energy storage power station, wherein the constraint conditions of the charge state and the charge and discharge power meet the constraint of the installation capacity of the energy storage power station; calculating the power supply load, investment cost, operation cost and power purchase cost of each power grid; and constructing a total cost function model, and solving to obtain a charging and discharging power optimization result of the energy storage power station and a load power optimization result participating in response by taking the minimum operation total cost as an objective function and utilizing various constraint conditions. By taking the minimum total cost as a target, the energy storage configuration capacity is reduced and the construction cost of a power grid is saved under the condition that the load requirement of the data center is met, the power utilization cost is saved by using the time-of-use electricity price, a theoretical basis and technical support are provided for urban multi-station fusion construction and operation, and the economical efficiency, environmental protection property and reliability of power station construction and operation are ensured.
