South The Hydropower Participation Electric Power Market Competition Coulometric Analysis And Countermeasure Suggestion

in February 2002 the State Council has released "Electric power Organizational reform Plan", has been clear about the electric power marketability reform direction, the electric power organizational reform general goals is:"breaks the monopoly, the introduction competition, raises the efficiency, reduces the cost, the perfect electricity price mechanism, the optimize allocation of resources, the promotion electric power development, advances the national networking, under the construction government supervision fair competition, the opening order, the healthy development electric power market system". Authorizes "South Electric power Market Construction Plan" according to the national electric power Regulatory committee, the south electric power market construction according to the start, the development, the mature three stage organization will implement. Because the hydropower itself characteristic complexity and is maintaining the electrical network safe steady operation aspect the important position and the function, many special questions need the special study.In the south electrical network region has the rich water and electricity resources, at present the hydropower proportion surpasses 1/3, south this was the condition which other region electrical network did not have, the hydropower has become the electric power market important participant.The south electrical network covers Guangdong, Guangxi, Yunnan, Guizhou, Hainan five provinces (area), Guangdong is the electric power expense wealthy and powerful family, the annual electricity consumption occupies the entire region above 57%, but a Guangdong energy lacks, needs to call in the massive energy, the western rich hydropower can therefore enter Guangdong. The hydropower enters the net competition to the order carry on under certain rule, this article the net region has the representative 22 hydroelectric power stations south the selection, has made the thorough statistical analysis to its electrical energy characteristic. The research adopts the method is mainly aims at its historical power rate the situation, the statistics calculates the boom year electric quantity, the ample flow year electric quantity, the average to come the water year electric quantity as well as even lopsided (average comes water year 80%) the year electric quantity, the recombination "South Electric power Market Construction Plan" the first batch thermal power surfer competition unit's related stipulation, the thermal power according to an annual average use hourage 5500 hour consideration, determines its power rate 15% for the thermal power competition electric quantity; Based on this through compared to elects to each kind of plan, to determine a just electric quantity reckoning allocative decision, namely: South hydropower participation the electric power market competition, take the multi-annual mean power rate 50% as the basic contract electric quantity, other 50% takes the competition invariable electric quantity, and to traded the electric quantity the decomposition adjustment to propose own view, to first batch participated in the competition the hydroelectric power station selection putting forward their proposal.After first batch competition power plant selection, has carried on the summary analysis to the selection hydropower and the thermal power surfer competition effect, mainly has analyzed in the extreme case, water, thermal power whether can adapt mutually, as well as satisfies the electrical network safety requirement.
