Method and device for evaluating installation scheme of inter-line power flow controller, and electronic equipment

Abstract

The invention discloses a method and device for evaluating an installation scheme of an inter-line power flow controller, and electronic equipment, and the method comprises the steps: calculating the power flow distribution of a regional power grid in a normal operation mode, and judging a key section which can be installed and a line with a heavier load of the section; determining a main control line and an auxiliary control line for each key section line; establishing an upper-layer power regulation and control optimization model and a lower-layer benefit optimization model; and according to a system operation boundary condition, substituting the capacity of each end designed by the IPFC into the upper and lower layer models for solving, and obtaining an optimal installation scheme. According to the method and device, an IPFC installation scheme evaluation problem is converted into a hierarchical model optimization solution problem, calculation is simpler and faster, and reference can be provided for planning and construction of a power transmission network.

Description

technical field [0001] The invention relates to the technical field of direct current transmission, in particular to a method, device and electronic equipment for evaluating an installation scheme of a power flow controller between lines. Background technique [0002] In the actual power grid operation, as the load continues to grow, the grid structure becomes more and more complex, and the uneven distribution of power flow has become an important factor restricting the transmission capacity of the power grid. The Interline power flow controller (IPFC) is a powerful flexible AC transmission control device, which can control the power flow in a directional way, and "transfer" the power flow of the heavy-loaded line to the light-loaded line, which is enough to realize the power flow between the lines. power exchange. IPFC can not only improve the line power, but also dynamically control the voltage, power angle and impedance of the system. [0003] At present, only the Marcy...

Problems solved by technology

Therefore, for the installation location and capacity of IPFC, most of the existing technologies do not have too much engineering experience, and the amount of power flow transfer is used as an evaluation index, so the economy and reliability cannot be guaranteed, and the evaluation basis for the operation capacity of IPFC is relatively simple. Difficult to use to guide engineering practice
