摘　　要：上网侧分时电价已在多个省份实施,现行的政策以"保持总体电价水平不变"为原则制定分时电价浮动比例,但由于供需形势和电源结构的不断变化,实际执行结果与设计方案差异较大,导致电网公司和发电企业的利益受到较大影响,部分省份暂停上网侧分时电价政策。此外,在实际操作层面,该原则也仅能给出分时电价浮动比例的比值关系,具体的浮动比例数值仍由政策制定者确定,存在一定的主观性。针对以上问题,以长期边际成本定价理论为基础,针对某省的实际情况,建立了分时电价浮动比例的计算模型,避免了浮动比例人为确定的不足。同时,设计了上网侧分时电价的调整机制,以动态调整方案取代现行的静态方案,发电公司和电网公司受分时电价政策的影响及时通过浮动比例联动方案和销售电价联动方案进行疏导,从而有利于分时电价政策的长久执行。In China, the time-of-use （TOU） electricity price at generating side has been implemented in multi provincial power grids, and according to current policy the floating proportion of TOU is drafted in the principle of keeping overall price level constant. However, in view of being continually changed power source slructure and situation of power supply and demand, there is evident difference between actual implementation results and designed TOU schemes, and it leads to obvious affection on benefits of transmission network companies and power generation enterprises, so that the execution of the policy of TOU at generating side is stopped in part of provincial power grids. Besides, on actual operation level, above-mentioned principle can only give the relationship of the ratio in the floating proportion of TOU and the concrete value of floating proportion of TOU is still determined by the policymaker, thus there is a certain subjectivity. In allusion to this problem, in accordance with pricing theory based on long-term marginal cost and according to actual condition of a certain provincial power grid, a calculation model of floating proportion of TOU is established to prevent the defect due to artificially drafting the floating proportion. Meanwhile, an adjustment mechanism of TOU at generating side is designed, in which the existing static adjustment scheme is siabstituted by dynamical adjustment scheme to alleviate the affections of TOU policy on generating enterprises and transmission network companies by coordinated floating proportion scheme and coordinated selling price scheme. The designed adjustment mechanism of TOU at generating side is favorable to long-term execution of TOU policy.
