<>开始考虑有8个清算价,后来看了英文版的题,</P>
< >( On the basis of the load forecast for the next period, the bids, the current outputs, the ramp rates (the changing rates of the output), the ISO chooses sectors or a certain proportion of a sector of each unit from the sectors of the lowest price to the ones of higher prices (see the annotation below) till the forecast load is met. The chosen sectors and proportion of sector of each unit form the pre-schedule (the initial version of the schedule). The price of the last chosen sector (the highest sector price) is called the market-clearing price (MCP) at which all the energy is bought..),,我们觉得应该只有一个清算价。 <p></p></P>
<> 于是有下面的答案:</P>
<P>第一问我们用excel解的,误差在0.1%内,</P>
<P>第二个问题对序外容量以实际报价补偿,对序内容量以实际报价与清算价的差价补偿。</P>
<P>第三问用c编程,搜索出力,步长取每组机组段容量的最大值,很快得出结果是303.</P>
<P>第四问首先用mathematica求出了在潮流的约束下的出力和的最大值为982.51mw,也即不阻塞的的负荷的最大值是982.51mw,所以第四问可调,用mathematica与c程序结合,得出阻塞费为12019.12元,</P>
<P>第五问用三的程序得出是356,考虑安全第一,求出限值百分比的最小值是0.496,得出阻塞费为4096.4元。</P>
<P>也不知道对不对,因为第一问的结果对四,五的答案有很大的影响!</P>
