Abstract
Quality of electrical energy generated in a power system plays a significant role in our life. We, electrical engineers, are responsible to ensure power quality which is supplied to the consumer side. For ensuring the balance between generation and load demand we need a control at the generation side called automatic generation control. From a definition point of view, we can say automatic generation control is a method for changing the power output and frequency of several generators at various power plants in response to load variations. This control can be done at the governor side and thereby controlling the prime mover speed. For multi-area interconnected power system tieline plays an important role in power transfer between control areas. Conventional power system uses AC tieline for interconnecting different areas. Here, we introduce High-Voltage DC (HVDC) tieline in parallel with AC tieline. Firstly, introducing a new model of HVDC tielink is more better than conventional model of HVDC tielink. A control strategy is introduced called inertia emulation control(INEC) for HVDC tieline control. The dynamic response of the power system can be improved using this new methodology in AGC. It improves the power transfer capability. In the present scenario, renewable energy resource integration into the conventional grid is a major challenge to power system. If we use this new HVDC technology in the power system, it is more advantageous to RE integration. That is control and operation become more flexible.
