Abstract

The invention discloses a multi-time-scale province-region-county integrated reactive power optimization method of an electric system. The method considers the yearly rule, the season rule, the monthly rule, the day rule, super-short-time built-in inertia rules and random components. The method can achieve multi-time-scale province-region-county integrated reactive power optimization, provides multi-time-scale continuous reactive voltage optimal configuration strategies, achieves reactive voltage optimal operation between various voltage classes in long periods, intermediate periods and short periods, improves the voltage qualified rate of the whole network, guarantees continuous, safe and stable operation of the power grid, provides theoretical foundations for setting up the operation mode of the power grid and reasonably and optimally utilizing electricity generation resources, and can effectively guarantee safe, stable and continuous operation of the power grid.

Description

technical field [0001] The invention relates to the field of reactive power analysis and optimization of electric power systems, in particular to an efficient multi-time-scale reactive power optimization method for provincial, prefectural and county integration. Background technique [0002] In the past ten years, the security and stability of the power system has increasingly become the focus of the industry. In modern power grids, due to the heavier load of weak systems and long lines, the transmission capacity of the power grid is getting closer and closer to its limit, making the stability of the system more prominent. Optimizing the operation mode of the power system can greatly improve the safety and stability of the power system, and the reactive power optimization of the power system is an important part of it, which involves large-scale, nonlinear, dynamic and discrete combinatorial optimization problems. The existing process is that the operator sets the initial v...
