| 摘要: |
| 输电网的资源有限性使得电力市场环境中的各交易方都面临输电阻塞的风险。从需求侧用户的角度分析阻塞风险，提出不仅发电公司要有计及阻塞风险的策略性报价．用户也应当考虑阻塞给自己带来的风险，策略性地决定购电方案。针对阻塞给用户带来的风险．构造了需求侧的购电策略模型，用户可根据各种购电方案下的收益期望值和收益标准差决定购电量．并进行了实例分析。用户主动调节负荷，有利于实质上缓解输电网的阻塞问题。 |

| Abstract: |
| The limitation of transmission network makes all traders in electricity market confront with the risk caused by transmission congestion.The congestion risk is analyzed from demand side.Both generation companies and consumers should reckon the congestion risk in bidding or purcha-sing strategies.A purchase decision model at demand side is constructed,with which consumers may draw up their energy purchase plans in terms of profit expectations and profit standard deviations in diffierent purchase conditions.An analytic example is put forward.The voluntary adjusting of power demands by consumers will mitigate the transmission congestion virtually. |
| Key words: electricity market,risk analysis,profit expectation,profit standard deviation,energy purchase strategy,demand side management, |
