Subsidy method, apparatus and device for high-cost unit to participate in spot market

Abstract

The invention discloses a subsidy method for a high-cost unit to participate in a spot market. Through access to subsidized electricity tariffs, the upper limit of the subsidy income and the upper limit of the subsidy value of the subsidy units to be subsidised are determined, calculating the total market income of the units to be subsidized, subsidise the ceiling on earnings. The minimum betweenthe difference in total market earnings and the ceiling on the value of the subsidy is the value of the subsidy payable. Provided is a method of targeted subsidization according to the actual situation of a high-cost unit, and by capping the benefits of subsidies, the upper limit of the subsidy value. At that same time, the value of the subsidy payable is obtain by taking a small amount of the subsidy. As excessive subsidy to that high-cost generating unit are avoided, the value of subsidies should be exported for staff reference, and the value of subsidies should be issued to the units to besubsidized according to the value of subsidies, which can offset the losses of high-cost units in the competition of spot market to a certain extent, pave the way for the improvement of the mechanismof the power market, and ensure the stable start of the spot market.

Description

technical field [0001] The invention relates to the field of electric power spot market, in particular to a subsidy method, device and equipment for high-cost units participating in the spot market. Background technique [0002] In the development process of the electricity market, the soundness and improvement of the market mechanism, and the production of the electric power industry in line with the development of the market all require a process of adaptation. At present, the power generation side participates in the Guangdong power market using the price difference trading model based on the government-approved on-grid electricity price. After the introduction of an independent transmission and distribution price sharing mechanism, it will gradually transition to the full electricity price trading model. Under the full electricity price transaction mode, all units will declare absolute prices in the market to participate in the competition based on their own power genera...

AI Technical Summary

Problems solved by technology

If appropriate subsidy measures are not adopted, a large number of clean energy generating units, such as comprehensive resource utilization units, coal-water slurry units, self-built dedicated line online units, and gas-fired units, will be at a disadvantage in market competition, which will eventually lead to long-term shutdown of the units. power plant failure

These units include gas-fired units and units in backward areas. Gas-fired units have a major impact on the safe operation of the power system. Insufficient capacity of gas-fired units may lead to insufficient peak-shaving capacity of the system during peak load hours, causing serious system security problems; Similarly, the closure of a large number of units and power plants in backward mountainous areas may also lead to potential insufficient system capacity
