基于节能发电调度的两部制上网电价机制设计

Design of Two-Part Grid Purchase Price Mechanism Based on Energy Conservation Generation Dispatching

上网电价机制设计是关系到当前节能发电调度能否顺利推行及未来成本型电力库能否平稳运行的关键因素。以实行两部制上网电价前后各相关主体的利益保持静态不变为原则进行上网电价机制设计,提出了电量电价和容量电价设计方案和调整机制,引入了供求关系调节系数、机组可用率调节系数及容量电费平衡机制,所提出的方案设计在当前节能发电调度及未来成本型电力库两个阶段均可起到保持现有利益格局、稳定市场的功效。

Design of grid purchase price mechanism is the key factor that relates to whether the energy conservation generation dispatching could be successfully carried out at present and the smooth running ,of cost-driven power pool could be implemented in the future. Based on the principle that the interests of relevant stakeholders are kept statically unchanged before and after the implementation of the two part grid purchase price, a mechanism for grid purchase price is designed, and the design schemes for capacity price and electricity quantity price as well as corresponding adjustment mechanism are proposed, and the regulating factors for supply-demand relationship, availability factor of generation units and electrical capacity charge balancing mechanism are led in. The proposed design schemes can play the roles of maintaining existing interest allocation pattern and stabilizing electricity market in both stages, namely the current energy conservation generation dispatching stage and the cost-driven power pool in the future.
