提出了基于未确知数的发电企业分段竞价策略形成的新方法,即采用未确知数表示市场出清价格、企业上网电量、企业发电成本等较为复杂的不确定性信息。针对未确知数基本运算结果与某些实际物理过程不相符合的缺点,提出了修正的同阶未确知数和同元未确知数的计算定义,并采用该定义得出企业的期望收益未确知数,为企业根据自身风险承受能力和市场情况形成最后的报价方案提供依据。该方法不需要对市场出清价格的分布进行假设,计算结果可以提供比传统方法更多的信息;高阶的未确知数可以更为精细地反映市场的真实情况,为发电企业提供更为详细的市场信息和备选方案。实际系统算例证明了该理论在竞价方案形成过程中的可行性与优越性。
A new method based on the unascertained number is proposed, which is to use the unascertained numbers to represent the more complicated uncertain information such as the market clearing price, the on-grid electricity consumption of enterprises and the cost of power generation in enterprises. Aiming at the shortcomings that the result of basic unascertained number does not accord with some actual physical process, the definition of modified same order unknowns and unary unknowns is proposed and the expectation The unidentified revenue provides the basis for the enterprise to form the final quotation scheme according to its own risk tolerance and market conditions. This method does not need assumptions about the distribution of market clearing prices, and the calculation results can provide more information than traditional methods. The higher order unknowns can more accurately reflect the real market conditions and provide more Detailed market information and options. The actual system example proves the feasibility and superiority of the theory in the formation of bidding scheme.
