Research On Pricing Theory Of Power System About Multi-Power

The purpose of the electricity market reform is to break the monopoly,im-prove efficiency,reduce the price of electricity,make power investors have reasonable rewards, make power industry has sustainable development and increase society's welfare finally.Pricing mechanism is the core problem of electricity market reform.The Scientific and reasonable price is not only beneficial to the power structure optimization,and can lead the market supply and demand balance,so can bring about the most effective use of the electric power resource.In the actual electricity market,Power plants tend to consider his own benefit maximization,use all sorts of market power,through the strategic offer earn extra profits.In our country,thermal power and hydropower have very large proportion at present power structure,but renewable clean energy have only a small proportion.Renewable Clean energy is developing quickly,it will occupy a bigger share of the market in the future,multiple power pricing and its mutual influence is now need to be consider.The Electricity Value Equivalent(EVE) Prieing Method is founded base on researching thermal pricing,it has many good characteristics than Uniform price and Pay As Bid(PAB).Right endpoints theory of EVE can inhibit behavior of declareing high price and holding leave capacity of the power investors,also content three principles of the market and give power investors for reasonable compensation.EVE in the Thermal power is proved reasonable and effective,so it is used for bidding on hydropower in this paper.At thermal power and hydropower jointing market,we use hydropowe first.Hydropowe price is measured by thermal price,making thermal and hydropower online bidding at the same time.This part is detailed description and though example proved the fine function of EVE right endpoints in hydropower maket.Conventional energy replaced by clean and renewable energy is inevitable trend.In recent years,nuclear power,wind powerand photovoltaic power generation are developed rapidly,but pricing of clean reproducible energy is founded relatively lags in our country.Our country maked stake electrovalence for wind power in 2009,it is promoting the development of wind power.But so far,stake electrovalences for nuclear power and photovoltaic power generation don't maked.Through comprehensive analysis,this paper suggest make stake electrovalence for nuclear power and photovoltaic power generation reference to wind power.
