Research On Facilitating The PV Consumption With Demand Side Management Strategy

Photovoltaic(PV)is a fast-growing energy source in recent years,and its penetration in power systems is increasing rapidly.Due to the inconsistency between power demand of the user and the PV output in the timing characteristics and the increasing of the Peak valley of demand side,the PV is abandoned seriously and how to facilitate the PV penetration in the power system is urgently needed to be studied.In this paper,the Demand side management(DSM)strategy was put forward to enhance the capacity of PV consumption,the main work includes follows:(1)Load forecasting in demand side management.The loading data of a residential area around Ohio State University were collected and a load forecasting method based on time series analysis was established.Load forecasting was carried out 24 hours a day on March 1,2016 in Ohio.(2)Energy consumption model of demand side load.Based on the ATUS time survey report and the sampled data set,a typical energy consumption event for a single house is defined.The determinants of energy events are determined,including the start time,duration and probability of occurrence of the event in the whole region,and the feasibility of the decisive factor of energy consumption event was verified by simulation.(3)Demand side load transfer strategy research.Firstly,the mathematical model of load transfer is optimized from the point of view of load transfer connection time.Secondly,the user' comfort model of the residential area,office area and industrial area were established.Finally,a user-centered pricing model was given.(4)Research on facilitating Photovoltaic Consumption with load management research.Firstly,the method of setting the target curve of load transfer was put forward.Secondly,the load transfer mode was obtained by simulation calculation.Finally,the optimization results of the load transfer strategy were evaluated.
