Renewable energy power generation consumption method based on multi-province distribution

Abstract

The invention discloses a renewable energy power generation consumption method based on multi-province distribution. The method comprises the steps of 1, calculating the renewable energy power generation capacity and the load power of provinces participating in consumption; 2, calculating social welfare functions of the provinces; 3, judging the consumption capabilities of the provinces; 4, according to the social welfare functions and the consumption capabilities of the provinces, allocating the consumption capacity of the provinces capable of independently consuming the renewable energy power generation capacity; 5, allocating the consumption capacity of the provinces incapable of independently consuming the renewable energy power generation capacity; and 6, repeating the step 5 until complete consumption. According to the method disclosed by the invention, the consumption capacity of the provinces participating in consumption is reasonably judged, and the consumed power is combinedwith the social welfare functions, so that the consumption efficiency and the consumption space of the renewable energy power generation capacity are improved, the economic exchange of a power receiving party and a power supply party of renewable energy power generation are promoted, the wind abandonment and light abandonment phenomena of the power supply party and the coal-fired power generationconsumption of the power receiving party are reduced, and the renewable energy utilization and the energy conservation and emission reduction are facilitated.

Description

technical field [0001] The invention belongs to the technical field of renewable energy accommodation, and in particular relates to a renewable energy generation accommodation method based on multi-province distribution. Background technique [0002] It is estimated that by 2020, the domestic installed capacity of renewable energy power generation will reach 680 million kilowatts, and the power generation capacity will be 1.9 trillion kilowatts, accounting for 27% of the total power generation; Stable operation has brought great challenges; at the same time, the large-scale development of renewable energy has put forward higher requirements for the power grid's cross-regional transmission capacity, power consumption space, and the level of power grid to accommodate renewable energy. [0003] The rapid growth of renewable energy installed capacity is not coordinated with the development plan of the power grid, and the development of the power grid cannot keep up with the grow...

Problems solved by technology

[0004] At this stage, the ways to consume renewable energy electricity include energy storage technology, multi-energy complementary mode, and demand-side response. Although these ways can promote consumption, the limitations of science and technology, the constraints of energy costs, and the stability of power quality and other factors , so that the distribution of renewable energy power generation is uneven, and the consumption cannot be completed in the power generation area, resulting in the phenomenon of abandoning wind and light, and cannot be distributed on demand on the power demand side. Storage and other processing, the operation is cumbersome, and the distribution of too little electricity causes fluctuations in the amount of renewable energy, which is not conducive to use; the consumption of renewable energy is an effective way to consume renewable energy through other provinces. Promote the consumption of renewable energy in the province and bring economic benefits to other provinces
