在配电侧电力市场中，微网用户与配电公司之间签订双边交易合约，约定交易电量和交易电价。以合约期经济利益为目标进行经济调度，建立了基于概率分布的调度优化模型并给出了基于置信水平的调度优化模型求解方法。同时，用期望成本确定最佳置信水平，提出了一种变置信水平优化策略。仿真算例证明了所提调度优化模型求解方法和变置信水平优化策略的可行性。
在配電側電力市場中，微網用戶與配電公司之間籤訂雙邊交易閤約，約定交易電量和交易電價。以閤約期經濟利益為目標進行經濟調度，建立瞭基于概率分佈的調度優化模型併給齣瞭基于置信水平的調度優化模型求解方法。同時，用期望成本確定最佳置信水平，提齣瞭一種變置信水平優化策略。倣真算例證明瞭所提調度優化模型求解方法和變置信水平優化策略的可行性。

In the distribution electricity market,a bilateral trade agreement containing transaction electricity and transaction price exists between microgrid users and power distribution companies.Aimed at optimizing the economic interest during the contract period,an economic scheduling model based on probability distribution is developed and the solving method based on confidence level is given out.Meanwhile,by determining the best confidence level with the expected cost,a variable confidence level optimization strategy is presented.Finally,the effectiveness of the presented model and the proposed optimization strategy are verified by simulation examples.
