Abstract

The invention relates to a power network planning construction method based on network reconstruction and optimized load-flow simulating calculation. The power network planning construction method based on the network reconstruction and the optimized load-flow simulating calculation comprises the steps that load-flow of a power system is calculated by a digital simulation module in a power network simulation platform, constraint of a future power network is set by an operator, interface service calls used for power network planning are increased, a network reconstruction subsystem obtains power network data, rules followed by the network reconstruction subsystem in calculation are determined, calculation constraint is determined, the network reconstruction subsystem acquires an optimal solution, artificial interfering correction is conducted to a network reconstruction result, the result is written into the power network simulation platform, an optimized load-flow subsystem obtains power network data, constraint is determined before the calculation of the optimized loading-flow subsystem, optimized load-flow calculation is developed, the result is exported and sent to the power network simulation platform, artificial interfering correction is conducted to the exported result, and the result after the artificial interfering correction is stored in the power network simulation platform. The power network planning construction method based on the network reconstruction and the optimized load-flow simulating calculation largely improves the working efficiency of power network planning and the efficiency of a power network operation mode, and thus a power network planning working process which is convenient and high in efficiency is created.

Description

technical field [0001] The invention belongs to the technical field of power system calculation and simulation, in particular to a method for constructing a grid planning based on network reconfiguration and optimization power flow simulation calculation. Background technique [0002] Grid planning, also known as transmission system planning, is based on load forecasting and power supply planning. Power grid planning determines when and where to invest in what type of transmission lines and the number of circuits to achieve the required transmission capacity within the planning cycle, and to minimize the cost of the transmission system on the premise of meeting various technical indicators. [0003] Power grid planning is classified according to time and can be divided into short-term planning, medium-term planning and long-term planning. The short-term plan is divided into 1-5 years, and the content of the plan is more specific and careful, which can be directly used to gu...
