Research On Correlation Problems Of Stored Energy Wind Farm Integration Into Power Network

In order to effectively improve the influence of the wind farm incorporation to the power system, unifies BESS/STATCOM unit and wind generator unit. A mathematic model of BESS/STATCOM based on park transform and an asynchronous generator based global dynamic mathematical model for wind power generation system are built. Based on these models, the simulation of active power output of a wind farm and terminal voltage of point of common coupling(PCC) with different wind speed is developed by using PSCAD, the result indicates the BESS/STATCOM unit's fast power regulation ability, enables the wind power generation unit to be possible to take the dispatch unit, moreover can obviously enhance the electrical network the stability and reliability; Based on the PSS/E platform, analysis the studied stored energy wind farm's impaction on the network various node voltage and the line transmission power influence, finally indicated the large capacity stored energy system could propose the wind field penetration obviously, improve the electrical network reasonable power distribution and the strong voltage support, guaranteed the electrical network the normal operation. This conclusion also has the positive enlightenment and the model function regarding the impetus wind power generation in the chinese characteristic strong intelligence electrical network construction advancement vigorously development.
