With the generalization of renewable power and distributed generation,there is an urgent need for a new energy storage system(ESS).For one thing,the new system can balance the peak-to-valley power supply ratio.For another,the new system can be a cushion to ease the power supply fluctuation caused by climate.High-Rise Pumped-Storage is a brand-new concept and could be a new form of energy-storage in the future.High-rise used to be the load center of energy consumption,whose potential on pumped-storage is greatly neglected.Thus,the pumped-storage system initially constructed for fire control and daily water supply can be used as a pumped-storage system power station when combined with BIPV and wind power system,to provide backup solutions when the bulk grid fail.The feasibility of High-Rise Pumped-Storage should be tested before design and economic benefit comes first.Thus,this essay is to present the research on High-Rise Pumped-Storage as follows:First,the research on the operation of ESS.This raises a user-side storage optimization market environment with the power to run the model and optimization methods,the use of existing timeshare purchase electricity use(TOU)pricing,charging and discharging efficiency energy storage system using the actual values are not the same.TOU deduced decision based on a combination of charge-discharge binary and under the common connection point of the two-way flow,the original problem is obtained quickly become a global optimal solution of linear programming optimization model.Second,the research on the optimization of daily operation.It is proposed as a future super high-rise pumped storage,a new form of user-side energy storage,to study its system model to determine the date of the system operation optimization objective function.TOU pricing mechanism proposed algorithm using the model optimization solution,and finally through the Jinmao Tower in Shanghai under the tariff example to do a simulation of pumping energy storage system.Do the preliminary model selection,parameter selection of seamless steel tubes,through matlab software is based on the calculation method of characteristics at different time to discard the needle off the maximum full load the minimum water hammer,and combined with the impact of turbines for solving large fluctuations in output during the unit speed change,draw reasonable needle of the case under the off-time and off to control the action time.Third,the pumped storage optimization system diagram structures is established by analyzing the universal energy storage system with super-high-rise,and then create the software user interface through the block diagram of the content.
