Problems solved by technology

In addition, the free use of schedulable loads and the superposition of conventional loads make the load curve show the characteristics of peaks and peaks, and the peak-to-valley difference of the power grid increases. If no adjustment is made, the pressure on the system's peak regulation and frequency regulation will increase.
According to the routine, it is necessary to build new frequency modulation and peak load generating units. If new units are built only to cope with peak loads, the economical and efficient operation of the system will not be guaranteed.

Abstract

The invention discloses a short circuit ratio-based multi-infeed ultra-high voltage direct current power grid converter reactive power configuration method. The method comprises the following steps that: step 1, adjacent date and historical load data and wind / light power generation power data are obtained; step 2, wind and light power generation power and daily load are predicted; sep 3, the equivalent daily load curve of a prediction date is constructed; step 4, the area of a wind power generation curve is calculated; step 5, heat storage capacity is calculated; step 6, an area under the loadcurve is solved through adopting a Monte-Carlo algorithm curve area solution method, and the heat storage capacity in an active power distribution network is matched with peak load; and step 7, an equal-area replacement method is adopted to reconstruct the equivalent daily load curve according to a matching result satisfying requirements. With the method provided by the invention adopted, a wind,light, storage, and heat multi-energy flexibly-complementary active power distribution load can be reconstructed more safely, economically, reliably and effectively; and a technical base and practical method can be provided for the safe, economic and efficient dispatching of the active power distribution network.

Description

technical field [0001] The invention relates to the technical field of active distribution network load reconfiguration in a power system, in particular to an active distribution load reconfiguration method based on wind, light, storage and heat multi-energy flexible complementarity, which belongs to the active distribution network network operation, control and scheduling. Background technique [0002] The development of distributed power can optimize the energy structure, promote energy conservation and emission reduction, and achieve sustainable economic development. In recent years, with the rapid growth of the penetration rate of distributed power in the distribution network, the development of energy storage, heat storage and electric vehicles, the traditional distribution network is gradually evolving into an active distribution network with many controllable resources. Its operation and management will also encounter many challenges. [0003] Due to the large netwo...
