Calculation Of Economic Benefit Of HESS For Improving Schedule Plan’s Credit Of Wind Farm Incorporated System

Wind Farm output inherent in half adjustable,half-controlled characteristics for wind farm integrated power systems has brought a great deal of trouble,while smoothing wind power balance between abandon wind has restricted wind power development and grid technology.Using rich wind farm power production of hydrogen from electrolysis of water,made of hydrogen(hydrogen)in the form of reasonable local stores,wind power when vacancies through hydrogen fuel cell devices into electrical energy is released,which coupled wind-hydrogen fuel cell energy storage energy system.According to Hydrogen Energy Storage System(HESS)economy,establish the credibility of HESS increased wind power grid dispatching plan economic efficiency calculation model.First,analysis HESS improve wind electric grid scheduling plans credibility of mechanism,proposed meter and the wind electric forecast output,and actual output and the scheduling output of hydrogen storage can system improve wind electric grid scheduling plans of credibility of charging and discharging price strategy;second,established meter and the HESS directly economic income and indirect economic income of HESS day income mathematics model,and meter and the HESS fixed cost and variable cost of HESS day cost mathematics model,this based Shang,Building improve wind electric grid scheduling plans of credibility of HESS day economic calculation mathematics model;last,for improve operation of efficiency and accuracy,enhanced research results of application value and general applicability,editor based on VC++ software platform prepared upgrade wind electric grid system scheduling plans credibility of HESS economic calculation software(HEBCAS),the software can automatically loaded processing wind electric data,and automatically divided hydrogen storage can filling,and discharge interval,and automatically return is hydrogen storage can system corresponding interval Shang of filling,and Discharge power,as well as economic indicators of hydrogen energy storage system.we used a specific example-a MW level wind farm power of Xinjiang forsimulation validation object,selected a days of wind electric forecast datas,and wind electric scheduling data and wind electric actual output data,on by built HESS improve wind electric grid system scheduling plans credibility of economic mathematics model for simulation validation,and for validation results respectively analysis has economic on wind electric forecast errors and scheduling errors of sensitivity,results showed that by established of HESS economic calculation model of correctness.Results for wind-hydrogen energy storage system set up in the early data for the economic evaluation of reference,for the premise of reducing abandoned air rate of large-scale grid-connected wind power expands the path.
