Conventional fuels are used as the main source of energy for producing and satisfying the demand for electricity. But the high cost, availability and harmful gas emission of conventional sources, challenged the future scope of these fuels. Distributed energy resources (DERs) like photovoltaic, wind energy, geothermal, tidal, biomass have gained the attention of power sector. These DERs can be installed as, small distribution systems or as smart grids or can be combined with the existing power system network as hybrid interconnected system to fulfil the needs of power sector. But these hybrid interconnected systems have its own limitations like load frequency control, voltage fluctuations etc because of which the share of these DERs in total power generation is not exceeding to 10%. This research work proposed a set point weighted two degree of freedom (TDOF) proportional integral derivative controller to improve load frequency control in a twoarea hybrid structure encompassing of solar & steam generation. To validate the dominance of TDOF controller results are rivalled with the Firefly algorithm tuned PID controller. Results of simulation reveal that the intended controller’s performance in restoring frequency to standard value is better than the existing controller.
