The invention relates to an electric quantity balance measuring and calculating method and a device. The method comprises the steps of obtaining the minimum generating capacity and the electric quantity balance difference coefficient of a whole-network traditional energy power supply under each typical day; based on a pre-constructed safety constraint unit combination model, according to the minimum power generation amount and the power balance difference coefficient, determining day-by-day predicted power generation amount of the whole-network traditional energy power supply in each typical day; according to all day-by-day predicted power generation amounts and a preset summation rule, determining month-by-month predicted power generation amounts of the whole-network traditional energy power supply in all typical days; and if each power balance difference coefficient is 0, the month-by-month predicted power generation amount is greater than the month-by-month basic power generation amount, determining the month-by-month power supply margin of the whole network traditional energy power supply according to the month-by-month available power generation amount, the inter-province month-by-month power transmission and reception amount, the intra-province month-by-month power transmission and reception amount and the month predicted power generation amount. By adopting the method ofthe invention, the precision and reliability of the monthly power supply margin of the traditional energy power supply of the whole network can be improved.
Description
technical field [0001] The invention relates to the technical field of power system dispatching, in particular to a method and device for measuring and calculating power balance. Background technique [0002] Power balance is an important part of power system operation arrangement, including power balance analysis and power balance analysis, and evaluates the possible annual power supply gap from the power supply adequacy and power supply adequacy respectively. Among them, the adequacy of power supply directly affects the utilization hours of each power generation subject, and has a greater impact on its economic benefits. Therefore, market players have higher requirements for the accuracy of power balance calculations. [0003] At present, in the annual operation mode arrangement, the basic idea of power balance analysis is to consider the three indicators of the power generation capacity of different types of power sources, the planned power capacity of purchased and so...
