Agc Unit Cost Of Power Plants Involved In The Electricity Market

Building-up the electricity market of power generation has changed electric system of our country being in motion and doing business way, But the operation way changing makes the tradition AGC be confronted with a series of problems. In this paper, talk about AGC of electricity market, expatiate the problem of the costs of AGC units participating in the electricity market. Proposed may "the electricity generation power transaction" realize between various power plants through the electricity generation enterprise group between double to win the mutual benefit, Also may carrying on the optimum composition and the rational distribution between the power plant under group, And falls through the power plant load economy dispatch realization energy conservation consumes.1,Introduce the origin and signification of electricity market; Fundamental condition of domestic and abroad electricity market, doing research for how electricity market influences the AGC operation. Analyze the basal principle of AGC controls, and have synthesized analysis to several kind control patterns at present AGC electricity market, As well as analyze how AGC is implemented in the power plant, Study the factors that can influence the running status of AGC units.2,Carries out analysis of the wheeling costs of AGC units, make preliminary discussion about the problem of how to do economic load dispatching for AGC unit of power plant, and how the AGC unit participates in electricity market, then based on that the five unit of Beilun power plant are calculation model, calculate the costs of Beilun power plant when AGC is putted in and when AGC is not in service, calculate the difference of them so as to evaluate the costs of AGC running.3,With the 37 fire coal unit of Zhejiang Energy Group Co., Ltd is calculation model, Analyze the cost change with optimize the load distribution between AGC units. By calculation, we got the conclusion: The dispatching signal arrives at power plant, every power plant optimize the load distribution between every AGC units, it can make an unit work as far as possible in the most economical working point, Cut down unit load's frequently change, Can reduce thermal efficiency loss thereby, reducing the operation cost of AGC unit.It's very important significance that AGC keeps the security; stable and economy running of power grid, but electricity system becoming market-oriented have brought forward the new request to AGC, Watch as a whole, the research going down the AGC operation in electricity market goes deep into our country fault very much. In this paper, make one general expound about the operation of AGC in electricity market, and make research about all above five problems, Have got certain significance result.
