Power Pool模式电力市场最优备用容量及定价

Power Pool 模式电力市场中最优备用容量的确定及其定价问题是非常重要和复杂的.文中在有关研究文献的基础上,建立了最优备用容量模型,并根据该模型研究了最优备用容量的定价和用户侧电价的确定问题.研究结果表明,某时段的最优备用容量完全由该时段的电力负荷需求量概率分布、单位余电损失和单位缺电损失决定;最优备用容量的价格可由实际上网电价和预测负荷需求电价决定;用户侧预期电价由带网损的结算电价、Power Pool合理收益和预期额外损失组成.

Optimal Standby Capacity and Its Valuation in Power Pool

The problem of optimal standby capacity and its valuation in Power Pool is very important and complicated. On the basis of researching literatures concerned, this paper constructs an optimal standby capacity model and researches the problem of pricing optimal standby capacity and determining power price on the user-side. The result shows that the optimal standby capacity at some period t is completely determined by the probability distribution density function of power load demand at this period and surplus power loss and insufficient power loss, and the price of optimal standby capacity is determined by real power price of entering power grid and the power price of forecasting load demand, and the expected power price on the user-side consists of the settlement price with grid loss on generation-side and reasonable gains and expected additional loss.
