An easy and simple electricity value equivalent (es EVE) method for day ahead pool purchase pricing of China is therefore presented in this paper. The es EVE method is different from two part and one part tariffs. It is more like the UK's method in form, but revised for China with some new concepts and procedure. The main contributions of it include: (1) Find two kinds of eigenvalue, namely EVEs, in an optimization model, (2) Define new concepts of virtual units and feasible region, (3) Twice merit orderings are employed successively to find marginal price. They are simple maximum and minimum comparison procedures and so on. The special economic significance of the method for China is discussed, and some suggestion for ESI restructuring based on es EVE method are provided. A case study is offered at the end of the paper.展开更多
