Benefits Analysis And Optimal Operation Of Pumped-Storage Power Station

With the constant development of grid-scale, regional power grid peak load and peak-trough difference increases, simply expand the installed capacity of power plants and grid transmission capacity is not the best method of the grid development. Therefore, distributed generation, load-side management and other new power-control means the current power grid has become the main direction of optimal operation of the study. However; for nearly a century has produced further study of pumped storage power station rarely occur. Make good use of pumped storage power plant efficiency unique peak load shifting, peak-trough fluctuation for improving the power grid to meet the demands of modern power regulation and control of the development of great significance. While the energy storage power plant units optimized allocation of operating conditions, but also a better use of existing units of resources, saving the secondary grid investment.Based on the above considerations, as an equivalent alternative to pumped storage power station units, the capacity of pumped storage power station on the effectiveness of calculation and analysis, and then the use of stochastic production simulation method to calculate the peak load shifting benefits to arrive at a cut-based peak valley filling unit to contribute to the principle of maximum efficiency, in order to Fenghua Xikou pumped-storage power plant in Ningbo, the actual operation of power grid as the background, using the principle of a case study to contribute to the development of its daily operation of the form of working condition. This will be the origin of pumped storage power station, control means and economic objectives combination presents a grid adapted to the characteristics and Ningbo, the economic operation of power plant's own means of control.
