具备调节能力的负荷参与现货市场将带来巨大的经济和社会效益，开展可调节负荷参与现货市场的多维度价值评估研究有利于推动可调节负荷参与现货市场。首先提出了基于场景模拟出清比较的价值评估方法；其次给出了可调节负荷参与现货交易的市场出清模型；再次从电网安全运行、调节能力、低碳减排和市场主体收益角度构建了安全性、灵活性、低碳性和经济性4个维度价值评估指标；最后通过改进的IEEE 30节点系统对可调节负荷参与现货市场前后2个场景进行了仿真，结果验证了所提评估指标和方法的有效性。

The participation of loads with adjustment potential in spot market will bring huge economic and social benefits. The multiple dimension evaluation research of adjustable load participation in spot market is beneficial for promoting adjustable load participation in the spot market. Firstly, a value evaluation based on scenario simulation and clearing comparison is proposed. Secondly, a market clearing model for adjustable load participation in spot trading is given. Thirdly, the value evaluation indicators of security, flexibility, low carbon and economy are constructed from the perspectives of power grid safe operation, adjustment capability, low carbon emission reduction and the revenue of market entities. Finally, two scenarios before and after the participation of adjustable load participation in the spot market are simulated using an improved IEEE 30-node system, and the results verified the effectiveness of the proposed evaluation indicators and methods.
