Description
Technical field
The present invention relates to a kind of wind-powered electricity generation system that is connected to the grid, relate in particular to the compensation deals system and the operation method thereof of a kind of wind-powered electricity generation online peak regulation service.
Background technology
Wind-powered electricity generation does not have the ability of conventional power supply peak regulation, frequency modulation, pressure regulation and aspect such as subsequent use, and the wind-powered electricity generation that the comparatively abundant area of China's " three Norths " wind-resources is developed all has anti-peak regulation characteristic.After the wind-powered electricity generation installation surpassed certain scale, other conventional power supply of electric power system replaced wind-powered peak regulation, frequency modulation, provides subsequent use, will cause operating cost to increase considerably.Power grid enterprises guarantee power system security in order to adapt to the characteristic of wind-powered electricity generation, when scheduling and operation, must take corresponding technical measures, the investment of the system that increases electric power and operating cost.
Conventional power supply provides more peak modulation capacity that the influence of its cost is mainly reflected in two aspects:
(1) opportunity cost.Because the peak regulation degree of depth increases, the annual utilization hours number of conventional power supply decreases, and average annual energy output also decreases.Because electricity power enterprise mainly relies on the sale electric energy and earns a profit, supposing that the reduction of energy output must cause negative influence to its profit under the constant situation of its cost of electricity-generating and profit margin.Can think conventional power supply unit because more peak regulation service is provided, tie up the space and the corresponding profit of electrical energy production, this part profit difference is called as opportunity cost on economics.
(2) operation increases cost (being that operating cost increases).For conventional fired power generating unit, because the frequent peak regulation of participating in needs the admission valve of unit frequently to open and close.Wearing and tearing have been increased on the one hand; Reduced the service life of unit, on the other hand, because the frequent degree of depth peak regulation of participating in; Unit can't operate in the optimum position of exerting oneself; The coa consumption rate of unit generation (cost) also can increase to some extent, the factor of comprehensive two aspects, and conventional fired power generating unit is participated in the operating cost that peak regulation will increase unit.
Therefore, for dredging cost, the excitation generating is ready to admit more windy electricity with enterprises of managing electric wire netting, need to formulate can reasonable compensation routine power supply peak regulation cost ethical policy.
Summary of the invention
The object of the present invention is to provide a kind of can science, valid measurement wind-powered electricity generation networks and aspect peak regulation, gives the compensation deals system of the wind-powered electricity generation online peak regulation service that conventional power supply brings influence, above-mentioned purpose realizes through following technical proposals:
The compensation deals system and the operation method thereof of the service of a kind of wind-powered electricity generation online peak regulation; It is characterized in that: the compensation deals system comprises the compensation management module; Opportunity cost administration module and increase cost management module, said compensation management module are connected with increase cost management module communication with the opportunity cost administration module respectively; Said compensation management module is used to calculate the expense that wind-powered electricity generation online peak regulation is served required compensation; Said opportunity cost administration module is used to estimate the conventional power generation usage unit and participates in the expense of the opportunity cost that degree of depth peak regulation produces and be transferred to the compensation management module; Said increase cost management module is used to estimate the conventional power generation usage unit and participates in the operation that degree of depth peak regulation produces and increase the expense of cost and be transferred to the compensation management module.
Above-mentioned purpose can also be further perfect through following technical proposals.
Said compensation management module calculates the expense that wind-powered electricity generation online peak regulation is served required compensation according to formula:
Wind-powered electricity generation online peak regulation is served the expense of the expense+increase cost of the expense=opportunity cost of required compensation.
