Problems solved by technology

[0004] In order to solve the shortcomings and deficiencies existing in the prior art, the present invention proposes a robust joint planning method for distribution of demand-side resources and intelligent soft switches, which solves the problem that there is currently no joint planning method that considers demand-side resources and intelligent soft switches. Uncertainties in intermittent distributed power output and user demand response in the above planning have not been reasonably resolved

Abstract

The invention discloses a demand side resources and intelligent soft switch distribution robust joint planning method, and the method comprises the steps: taking the minimum annual comprehensive cost of a power distribution company as a target, and putting forward a demand side resource sand intelligent soft switch deterministic planning model construction method; based on a polyhedron linearization skill and an equivalent substitution technology, providing a linearization method of the deterministic planning model; based on historical data analysis, providing distributed power supply output and demand side resources response result uncertainty processing method, and providing a demand side resources and intelligent soft switch distribution robust planning model construction method for the two uncertainties; and on the basis of a column sum constraint generation algorithm, providing a solution method of a distributed robust planning model, so that a joint planning result of the demand side resources and the intelligent soft switch is obtained. According to the technical scheme provided by the embodiment of the invention, advantage complementation of different planning objects is realized, the economical efficiency of the planning scheme is ensured, and the consumption capability of the distributed power supply is also improved.

Description

technical field [0001] The invention belongs to the technical field of joint planning of grid-side equipment and load-side resources of a power distribution system, and relates to capacity configuration and location selection of intelligent soft switches and demand-side resources. Background technique [0002] Under the background of global shortage of energy resources and intensified environmental pollution, vigorously developing green, low-carbon and sustainable energy has become the consensus of all countries in the world. As one of the important means of renewable energy utilization, after a large number of distributed power sources are connected to the distribution network, their volatility, intermittency, low controllability and other issues have brought great challenges to the safe and reliable operation of the distribution network. In order to solve this problem, flexible interconnection technology represented by intelligent soft switch and demand-side resource manag...
