Abstract

The invention discloses a multi-mobile energy storage vehicle path planning method, system and device, including the following process: calculating the peak variable load power of each station area on the day; judging the total capacity of the energy storage vehicle and the sum of the variable peak load power of each station area If the total capacity of the energy storage vehicle is not greater than the sum of the variable peak load power of each station area, turn to the step of establishing a dispatching model; establish a dispatching model with the goal of maximizing the total load reduction; use the particle swarm algorithm to solve the dispatching model, and obtain Scheduling parameters. The invention can respond to the load in time, improves dispatching efficiency, and reduces additional costs; fully considers factors such as charging and discharging time and displacement time of the energy storage vehicle, so that the dispatching method tends to be more reasonable and more in line with the actual application scene.

Description

technical field [0001] The invention belongs to the technical field of optimal scheduling of energy storage vehicles, and in particular relates to a path planning method, system and device for multiple mobile energy storage vehicles. Background technique [0002] With the development of the economy, the demand for electricity has increased significantly, and the requirements for power quality are getting higher and higher. The load distribution in the same area is very different, resulting in insufficient capacity of some box-type transformers during peak hours and heavy overload problems, and light-load or no-load conditions during the rest of the time, and low equipment utilization levels, which affect the economic benefits of distribution network investment. [0003] The mobile energy storage vehicle uses a standardized container as a carrier and a motor vehicle as a means of transportation. As a highly flexible resource, it can effectively solve the above problems. By c...
