Inter-line power flow controller site selection method and device and electronic equipment

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
