Abstract

The invention relates to a method of the field of electrical power system planning and computational analyzing, and in particular relates to a method for checking short-term trade plan safety. The method comprises the following steps of: 1, short-term trade plan load flow calculation; 2, short-term trade ground state load flow analysis; 3, short-term trade plan static state load flow analysis; 4, short-term trade plan impact assessment; and 5, short-term trade parallel check. The method for checking the short-term trade plan safety provided in the invention is easy to realize, and moreover, power grid load flow which reflects the execution condition of short-term trade can be obtained; and the requirements from aspects of energy conservation, environmental friendliness and safe, stable and economic operation of a conventional power grid on technological innovation are satisfied.

Description

technical field [0001] The invention relates to a method in the field of power system plan preparation and calculation analysis, in particular to a method for security check of short-term transaction plan. Background technique [0002] With the rapid development of large-scale interconnection of the power grid, the power grid will form a "three vertical and three horizontal" UHV power grid as the backbone grid structure, an AC / DC system with the highest voltage level, the largest transmission capacity, the most advanced technology, and the most complex operating characteristics in the world. Hybrid grid. With the advancement of UHV power grid construction, and the increasing operating pressure brought about by the application of a large number of power electronic components such as DC transmission and FACTS, and the large-scale access of wind power and photovoltaic new energy sources, the electrical connection of the entire network is becoming increasingly close, and the cou...
