Abstract

The invention relates to the technical field of power distribution optimization, in particular to a power distribution stochastic optimization planning method and device based on an improved ant lion algorithm, and the method comprises the steps: constructing a multi-objective function of a power distribution system integrated with a photovoltaic distributed power generation power supply and a distributed static compensator; and representing random characteristics of distributed photovoltaic and load demands in each season according to historical data, determining MALO parameters, performing iterative search solution on a multi-objective function by using an improved ant lion optimization algorithm, and determining an optimal planning scheme of the power distribution system. According to the method, a multi-objective function, including cost reduction, voltage distribution reduction and stability index improvement, is established under the condition that the solar irradiance and the load demand with parameter changes in four seasons of summer, winter, spring and autumn are considered in a combined manner. An improved ant lion optimization algorithm is provided, and the basic search capability of the ant lion optimization algorithm is improved by using two strategies so as to obtain an ideal planning scheme.

Description

technical field [0001] The invention relates to the technical field of power distribution optimization, and relates to a random optimization planning method and device for power distribution based on an improved antlion algorithm. Background technique [0002] The combination of renewable distributed generators and shunt compensators is an effective technical and economical solution. Distribution flexible AC transmission systems (D-FACTS) are widely embedded in the distribution network. D-FACTS includes many controllers such as Distribution Static Var Compensator (D-SVC), Unified Power Quality Conditioner (UPQC), Distribution Network Distributed Static Compensator (DSTATCOM). [0003] Distribution Network Distributed Static Compensator (DSTATCOM) is superior to other shunt compensation devices due to the system's fast response to controllable voltage injection or absorption of reactive power, as well as the mitigation of system harmonics, load balancing, and greatly improve...
