The measuring and calculating method comprises the steps of 1, preparing basic data including new energy data, load data, inter-provincial tie line data and section data; 2, constructing a power grid partition model; step 3, maintaining a power grid operation mode, and configuring operation constraints of conventional units in each partition according to an actual power grid conventional unit operation mode; step 4, creating a case, configuring corresponding calculation data according to case calculation requirements, starting calculation and checking a result; according to the steps, an optimization model containing unit start-stop constraint is established with the maximum new energy generating capacity as an optimization target, and a hybrid particle swarm optimization algorithm is adopted in a new energy consumption calculation method. The hybrid particle swarm algorithm adopted by the invention not only has the advantages of a conventional particle swarm algorithm, but also is faster in the aspect of calculation speed and more accurate in the aspect of calculation results than the conventional particle swarm algorithm.

Description

technical field [0001] The invention relates to the field of measurement and analysis of new energy consumption, in particular to a new energy consumption measurement method and system based on a hybrid particle swarm algorithm. Background technique [0002] With the rapid development of new energy sources such as wind power and photovoltaics in China, under the background of the contradiction between the large-scale integration of new energy into the grid and the difficulty in absorbing new energy in the power grid, it is necessary to continuously improve the level of new energy consumption in the power system and reduce the amount of abandoned wind and photovoltaic power. Significant challenges for scheduling agencies. [0003] At present, the research on the analysis of new energy consumption capacity at home and abroad mainly focuses on the qualitative analysis, and there are few studies on the quantitative calculation method. In the modeling method that uses the new en...

Problems solved by technology

In the modeling method of calculating the new energy consumption capacity with the calculation model of the new energy consumption capacity, the typical daily analysis method cannot reflect the daily new energy output characteristics, load characteristics and the differences of the whole network unit combination within a period of time. Results are often too conservative and cannot be used to guide annual / monthly grid operation optimization
