Title The Intelligent Scheduling Research for Large Data-Center Load

Abstract The proportion of data-center load in electric terminal devices is growing year by year,and the data-center load has regional relevancy,which can be used as a kind of special demand response resource put into the power system dispatching, adjusting the output of the power system load node where the data-center load is located by optimizing the data network running state to enhance the system ability to cope with tide fluctuation and improving the efficiency of the system。On the basis of in-depth analysis of the data-center load and the load balancing scheduling technology of cross-regional data-center load,with the data-center load as control object,this dissertation analyzes the mode and method to improve the efficiency of power system operation by optimizing the running status of data network。

This dissertation firstly establishes a power model and delay constraint model of data-center load,and based on the load balancing model,deduces the constraint model of power relations between the cross-regional data-center load。On this basis,this dissertation puts forward the optimization scheduling model and algorithm of data-center load under the double network consisting of the power system network and the data network, gives the Method of solving the model based on general ac optimal power flow optimization algorithm of matpower toolbox,and analyzes the error of the optimal scheduling model。 At the end,The case study shows the effectiveness of the optimization scheduling model and algorithm of data-center load under the double network。

Keywords data-center load ,demand response,power relations, double network,optimization scheduling
