Abstract

The invention discloses an inter-line power flow controller site selection method and device and electronic equipment, and the method comprises the steps: calculating the power flow distribution of a power grid in a normal operation mode, and judging a key section and a heavy-load line; aiming at the N-1 operation mode of the key section line, a line power flow and a bus voltage change rate matrix at two ends of the line are calculated, and the change rate matrix is normalized; and meanwhile, a hybrid direct current access receiving end power grid scheme optimization model is constructed in combination with the power transmission line distance, an IPFC access power grid site selection optimization model is solved, and an optimal installation branch is obtained. According to the method, an IPFC site selection optimization problem is converted into a single function network access optimization problem, the 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 site selection method, device and electronic equipment for an inter-line power flow controller. 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 substation project in t...
