Optimal scheduling method of smart power grid

Abstract

The invention relates to an optimal scheduling method of a smart power grid. The method comprises the following steps: acquiring power grid information, and performing data preprocessing on the acquired power grid information; preparing scheduling basic data, wherein the scheduling basic data comprises national scheduling basic data, branch scheduling basic data and provincial scheduling basic data; constructing a power grid security constraint energy-saving scheduling model according to the acquired power grid information and scheduling basic data; performing index evaluation on the power grid security constraint energy-saving scheduling model and the scheduling optimization strategy thereof, comparing the power grid security constraint energy-saving scheduling model and the scheduling optimization strategy with an established optimization target, and issuing and executing if the requirements are met; and storing the executed scheduling optimization result into a strategy library. According to the method, a characteristic scene used as required can be formed through flexible configuration of an optimization target and constraint conditions so as to meet different scheduling requirements, so that the large-scale optimization advantage of large-scale power grid scheduling can be fully exerted, the model construction difficulty can be reduced, and the solving efficiency can be improved.

Description

Technical field [0001] The invention belongs to the technical field of power grid operation, and specifically relates to an optimized dispatch method of a smart grid. Background technique [0002] In power energy management, power dispatch is an important part. The preparation of day-ahead power generation plans is an important daily business of dispatch centers at all levels. Security Constrained Economic Dispatch (SCED) is to support this business, promote grid energy conservation and emission reduction, and ensure the safe and stable operation of the grid One of the effective technical means. However, the conventional processing objects of SCED are all types of units with a single dispatching right in the same load balancing area. According to the domestic power grid dispatch organization mode, there is a special situation in the northeast, northwest and central China sub-centers of the State Grid, that is, the same dispatch area contains a large number of units belonging to ...

Problems solved by technology

When the ratio is large, the unit with fixed output will significantly reduce the regulation capacity of the whole network and may cause the organization responsible for balancing to bear too much balancing pressure

At present, it is not uncommon for sub-centers and provincial planning coordination work involving the safe operation of power grids to be carried out in actual production. Most of these coordination tasks rely on manual labor, resulting in complicated and cumbersome work processes
