山东电力市场模拟运行期间发生了因竞争而产生的边际电价持续下滑、既背离发电成本又不满足电能的市场供求关系的现象.文中指出产生这种现象的主要原因是当前电力市场的不完全性和山东电力市场规则中存在有能导致恶性竞争的条款.由于没有实现厂网分开,发电厂更注重的是发电计划的完成而非利润的高低.电力市场的竞价规则把合同电量和竞争电量绑在一起进行竞争,其结果是较高的报价不仅使电厂得到的出力低甚至可能停机.在市场竞争中为了避免停机损失和保证发电计划的完成,只得降低报价.还讨论了电力市场交易,边际电价与供求关系等问题.
山東電力市場模擬運行期間髮生瞭因競爭而產生的邊際電價持續下滑、既揹離髮電成本又不滿足電能的市場供求關繫的現象.文中指齣產生這種現象的主要原因是噹前電力市場的不完全性和山東電力市場規則中存在有能導緻噁性競爭的條款.由于沒有實現廠網分開,髮電廠更註重的是髮電計劃的完成而非利潤的高低.電力市場的競價規則把閤同電量和競爭電量綁在一起進行競爭,其結果是較高的報價不僅使電廠得到的齣力低甚至可能停機.在市場競爭中為瞭避免停機損失和保證髮電計劃的完成,隻得降低報價.還討論瞭電力市場交易,邊際電價與供求關繫等問題.

During the simulated running of Shandong Electricity Market, an abnormal phenomenon occurs,I.e., the marginal prices of electricity produced by rivals were continuously descending. The marginal price of electricity neither obeyed relation between electricity supply and demand, nor conformed to the generating-power-cost. In this paper, the reasons of continuously descending of marginal price in Shandong Electricity Market are analyzed. The marginal price of electricity market and the relation between supply and demand, the incompleteness of electricity market at present, the trade rule of electricity market and the unfair competition of rivals are discussed.
