Application And Research On Energy-Saving Generation Dispatching In Power Market Environment

Firstly, the paper anlysises basic states of current power market in China,then, based on the principle of energy-saving generation dispatching and actual situations of Chinese power system operation and dispatch, the paper makes a thorough research on application of energy-saving generation dispatching under the environment of junior power market. Combining with basic states of Hunan power grid, the paper launches a research on energy-saving generation dispatching and deducing hydroelec spinning reserve based on principles of energy-saving generation dispatching.Finally, basic frame work and development of energy-saving and generation dispatching technology system based on J2EE is designed.The essential of energy-saving generation dispatching is, according to the principle of energy-saving and economy and dispatching renewable resource in priority,sorting generators by its energy consumption and emission and dispatch fossil resource generator in order to minimize resource consumption and emissions.Based on anlysis of current power market,the paper researches basic application of Energy-Saving Generation Dispatching in power system from three aspects such as short-time power load forecasting,designing of generator sorted table and emission model.Strengthen of interconnected super-grid presents higher requirements as for power grid security, stablitity and economy. The accuracy of power grid's spinning reserve becomes an important way to keep the grid secure.Base on research of spinning reserve forecasting methods currently,methods such as linearization, polynomial fitting, similar-day selection and probability statistics and so on are proposed in the paper.On the basis of the above-mentioned theory research and combined with research subject of Hunan power grid,the paper elaborates the research findings of energy-saving generation dispatching and deducing hydroelec spinning reserve based on principles of energy-saving generation dispatching. The research refers to such aspects as spinning researve forecasting and distribution, disposal of constraint condition, examine of AGC generator and evaluate benefit of researve.To follow, considering current states of power system dispatching in our country, research on how to revise quoted price by considering factors of energy consumption, loss and emission. The paper proposes to sort generator by its price by introducing energy consumption factor,loss factor and emission factor into generation biding rules.Collective model of Energy-Saving Generation Dispatching and Generation Biding is proposed to conduct as the basis of Energy-Saving Generation Dispatching. The example demonstrates that the method can achieve the goals of energy-saving,environmental protection and economy more effectively.Finally, basic frame work energy-saving and generation dispatching information management system based on J2EE three-layers architecture is designed and the realization of systematic functions modules is described。The J2EE based systematic software designe, database design and security design are provided。Research findings in this paper possess vital theoretical research meanings and utility value, it provides a feasible plan for the application of energy-saving generation dispatching and development of its technology system.It benefits greatly the optimization of social resources allocation in entire country, reducing of emissions of pollutants, and advancement of the development of power industry.
