Problems solved by technology

Since the proposal of the "30·60 dual-carbon" goal, it has become an irreversible trend for large-scale new energy to be connected to the power system, which has significantly increased the uncertainty of the power system at both ends of the "source" and "load". In the case of operation, it is easy to have abnormal conditions such as voltage and power exceeding the limit, which will increase the risk of system operation. In severe cases, it is easy to cause chain failures and cause power grid blackouts

Abstract

The invention relates to an electric power system differentiation planning technology, in particular to a core backbone network frame construction method based on a risk theory, and the method comprises the steps: constructing an electric power system safety risk assessment index system based on the risk theory; calculating the weight of each index based on a CRITIC weighting method; and completing risk assessment through a probabilistic load flow calculation result, constructing a core backbone network frame search model by taking the minimum sum of the comprehensive risk level and the length of the core backbone network frame as an objective function; solving the constructed model based on an improved fireworks algorithm, and repairing the net rack connectivity through a Floyd-Warshall algorithm to obtain a core backbone net rack construction scheme. According to the method, risk factors are fully considered in construction of the core backbone network frame, the adverse conditions of voltage out-of-limit, power out-of-limit and the like are effectively improved, and the risk level of operation of the core backbone network frame is reduced. The risk level of the power system under the large-scale new energy access trend is reduced, and the disaster resistance of the system is improved.

Description

technical field [0001] The invention belongs to the technical field of power system differential planning, and in particular relates to a method for constructing a core backbone grid based on risk theory. Background technique [0002] In order to improve the power grid's ability to resist natural disasters, the power grid company proposed the concept of differential planning. The purpose of differentiated planning is to ensure continuous power supply to important loads in the event of major natural disasters or major accidents, and its core content is the construction of the core backbone grid. Since the proposal of the "30·60 dual-carbon" goal, it has become an irreversible trend for large-scale new energy to be connected to the power system, which has significantly increased the uncertainty of the power system at both ends of the "source" and "load". In the case of operation, it is very easy to have abnormal conditions such as voltage and power exceeding the limit, which ...
