Optimization Of Daily Dispatch Arrangement Before Day-Ahead Transaction Being Opened

Along with the restructuring of the electric power system and the reforming of the electric power industry in China, power system operation is striding forward to a ordered market environment of competition while monopoly will be removed in steps. However, the above competition environment brings a lot of inconsequence and imperfection in system, regulation and precepts for the gigantic interconnected power system. How to make the establishing process of electricity market adapt to the situation of our country, it is necessary to learn more domestic and overseas experiences and lessons in electricity market reforming process, to follow both the general rule of market economy and the special rules of power industry development. The importance of sustainable development for power industry must be emphasized. The approach leading to separate governmental functions from enterprise management is explored, we hope that along the approach, a ordered, dependable, equitable, healthy developing market system can be upbuilt.The region electricity market is already begin to make experiments in China. Northeast region electricity market attempts to open the annually contract, monthly contract and generate right trade firstly, the day-ahead, real time, the bilateral transaction and so on will be open for future time. Thus, the day-ahead transaction doesn't come in fact now.By analyzing the daily dispatch planning and its optimization model before day-ahead transaction being opened, the actual demand of making experiments in Northeast region electricity market will be well satisfied.Before day-ahead transaction being opened, daily dispatch arrangement has its own particularity. It is necessary to fulfil surely the daily generating electrical energy divided from long-term contract (including annually contract and monthly contract) for each competing power plant. What's more, the daily load ratio of the competing power plants should be accordant to each other in order to materialize the principle of"equity, impartiality and publicity". In optimization model for daily dispatch planning before day-ahead transaction being opened, the reflection of above particularities are focused on the aspect of equality...
