Load curve adjustment-oriented active power distribution network simulation optimization operation method

Abstract

A load curve adjustment-oriented active power distribution network simulation optimization operation method comprises the steps of obtaining basic data, setting convergence conditions, constructing and solving an upper-layer optimization model, constructing and solving a lower-layer first-stage optimization model and a lower-layer second-stage optimization model, and obtaining benefits of a virtual power plant, a scheduling scheme of resources in the virtual power plant, a final optimized load curve and the like. The method has the advantages that active management strategies and management means possibly adopted by a power distribution system dispatching center in the system operation process are considered on the basis of a traditional load curve prediction result, the dispatching potential of various active resources in a power distribution network is fully excavated, the virtual power plant serves as a regulation main body, the adjustment effect of the virtual power plant on the load curve under the active management strategy is simulated, the load curve is further optimized, and a load demand curve which better fits the actual operation of a power grid in the future is obtained, so that support is provided for follow-up accurate guidance of power distribution network planning construction and operation scheduling.

Description

technical field [0001] The invention belongs to the technical field of electric power distribution, and in particular relates to an active distribution network simulation optimization operation method oriented to load curve adjustment. Background technique [0002] The rapid economic development has led to an increasing social demand for electricity, but it also leads to peak loads and excessive peak-to-valley differences in the power grid, which poses challenges to the safe and stable operation of the distribution network. Therefore, corresponding measures will be taken during the actual operation of the distribution network. The optimization target of the load curve is adjusted to maintain the safe and economical operation of the power grid. On the power supply side, more and more experts and scholars have paid attention to smoothing the load curve through the joint optimal dispatch of distributed power generation devices and energy storage devices; on the user side, most ...
