Online optimization simulation system for complex distribution network

Abstract

The invention relates to an online optimization simulation system for a complex distribution network, comprising a data layer, an encapsulation layer, and a front end. The system is characterized in that the data layer, the encapsulation layer and the front end are connected in sequence; the data layer is used for acquiring online data and local data of a distribution network and initializing the online data and the local data of the distribution network; the encapsulation layer is used for encapsulating simulation calculation functions into simulation services (namely, one simulation calculation function corresponds to one COM component) and automatically matching out an optimal algorithm to solve an objective function minimum model; and the front end is used for providing a unified human-computer interaction unit to call the simulation services of the encapsulation layer. With the system provided by the invention, the online data of a distribution network can be extracted, parsed and cleaned. A service-oriented optimization calculation architecture is designed, and an optimization calculation method based on automatic matching of multiple algorithms is put forward. Global multi-mode and regionally-accurate online continuous optimization simulation of a large-scale complex distribution network is realized, and the operation efficiency and decision analysis level of a complex distribution network are improved.

technical field [0001] The invention relates to a distribution network optimization simulation system, in particular to an online optimization simulation system for complex distribution networks. Background technique [0002] With the increasing investment in distribution network construction in recent years, great progress has been made in the construction and transformation of distribution network in my country. The grid structure of distribution network has been greatly improved. The characteristics of large scale, many nodes, miscellaneous equipment, and multiple operation modes are becoming more and more prominent: a large number of distributed power sources, micro-grids, large-capacity chargers, and energy storage systems are connected to the distribution network, and the operation modes are becoming increasingly complex; network wiring is changed from the original Some single-power single-radiation and hand-in-hand methods have developed into dual-power ring networks an...

Problems solved by technology

[0003] At present, the distribution network optimization simulation is more offline, and the response speed to the complex and changeable distribution network is insufficient, with hysteresis, the processing capacity of the large-scale online data of the distribution network is insufficient, and the safety production and economic run as a guide

At the same time, the optimization function and goal are single, the optimization algorithm is inefficient and the calculation results cannot reflect the actual state of the site, it is difficult to deal with large-scale, complex and changeable distribution networks, and it has a considerable adverse impact on the optimal operation control of the distribution network.
