It is necessary for the Power system to manage distribution services efficiently in order to maintain reliability. One of the distribution services is frequency regulation to besupplied by the electricity market participants. For regulating frequency, it is necessary to maintain the balance betweendemand and supply in real time. This paper develops a newcontrol strategy for two connected systems with HVDC for participating in primary load- frequency control. The basicconcept presented in this paper to improve frequency responses through two connected system with HVDC system. Theproposed control technique boosts the operation of the governor controlling frequency in situations which it cannot compensate frequency drop because of large load power. The performance of control system has been validated by simulations of normal operation and overloads in MATLAB/SIMULINK.
