The present invention relates to a distributed photovoltaic and gas-electricity hybrid capacity planning method and system of a multi-energy complementary system. The distributed photovoltaic and gas-electricity hybrid capacity planning method of the multi-energy complementary system includes the following steps that: an original scene data set is constructed according to the illumination intensity data of unit statistical periods in a total statistical period and the load curve data of the multi-energy complementary system in the unit statistical periods, wherein the original scene data set includes a plurality of illumination intensity data and a plurality of load curve data in the unit statistical periods; scene reduction is performed on the original scene data set, so that two illumination intensity data and two load curve data of each unit statistical period can be obtained, and the two illumination intensity data and the two load curve data are separately inputted to a multi-energy complementary system capacity planning model; and a capacity planning parameter which makes the multi-energy complementary system capacity planning model obtain a minimum value is calculated, and distributed photovoltaic and gas-electricity hybrid capacity is planned according to the capacity planning parameter.
Description
technical field [0001] The invention relates to the technical field of energy dispatching, in particular to a distributed photovoltaic and gas-electricity hybrid capacity planning method and system for a multi-energy complementary system. Background technique [0002] The comprehensive utilization of multi-energy complementary distributed energy is an important way to efficiently utilize clean energy and renewable energy. Among the many multi-energy complementary system forms, the regional multi-energy complementary distributed energy distribution system including distributed photovoltaic power generation and "gas-electric hybrid" is a typical form. The energy conversion and interconnection between them realize the coordinated operation of the distribution network and the natural gas network. Rational capacity planning of regional multi-energy complementary systems with distributed photovoltaics and gas-electricity hybrids can improve the ability to accommodate distributed ...
