Implementation Of Tangshan Grid Residential Time-sharing Electricity Price Feasibility Study

With the rapid development of tangshan residential and industrial power,the traditional power supply mode can not accommodate with the rapid development of electric.It worth to reflect on how to ease the critical electricity supply,exploring the method of improving the efficiency of electric and decreasing the power consumption in the peak-load time.In Tangshan,Time-of-use price of electricity just used in industry,and brownouts happen frequently.The power demand side management is on junior level.TOU(Time-of-use)power price is one of the effective measures in DSM(Demand Side Management).Through exerting the effect of price lever,power consumers will change their power consuming mode so as to be beneficial to flat the load curve.This paper study on the strategy of TOU price of electricity in Tangshan,measure the user spending and power grid corporate earnings,analyses the formulation principles and operational risk of the strategy.nowadays,the TOU price has been used in Tangshan,however there are still some problems.First,the peak and valley periods division lack of a scientific basis,the function of load shifting is not too obvious;Second,the effect of TOU price policy has lagged far behind,there are many risks of the grid corporation.It turns out that the strategy has not increased residential electricity consumption,and the effect of valley filling is not comparatively obvious.
