The designed hybrid generation system (HGS) not only consider the voltage condition of connection point but also do limit output profile by following the transmission system operator’s directions. Therefore, when developing large-scaled system including a number of HGS, appropriate compensation strategy based on the system components and impacts should be formulized with considering inner system’s characteristics. The ESS operation plan in HGS should be supported by precise voltage expectation method because the system has large physical areas: it includes almost 150m DC section. Especially, since the previous system is not considering power limiting method at the DC section which is integrated with wave generators, an appropriate ESS compensation could provide a lots of solutions such as power control and quality issue. In this paper, an active power control algorithm with expected voltage based on the DC power flow is introduced, and imposed to the simulation process that is performed on EMTDC environment. Further, the comparison with the normal control process is carried out based on the composed layout in ongoing project.
