This paper presents a comprehensive study on dynamic performance of a more realistic power system with diverse sources in each area and interconnected via parallel AC/DC transmission links. The power generation in each area is based on diverse sources such as thermal, hydro and gas. To carry out the investigations, optimal Automatic Generation Control (AGC) regulators are designed and implemented by considering an example of a two area power system for 1% step load disturbance in one of the control areas. In order to assess the improvement in stability of this realistic power system with DC link in parallel with AC tie-line as interconnection, eigenvalue study is also conducted. It has been shown that the transient response of power system subject to a step load disturbance is sluggish/poor in the presence of hydro as one of the diverse source in the power system. But an appreciable improvement in system dynamic performance is achieved by considering parallel AC/DC links as interconnection between areas rather than using AC tie lines only.
