Integrated PV system with Optimal Reactive Power Dispatch for Voltage Security using JAYA Algorithm

The major concern in the field of power system is the voltage stability and transmission efficiency. Many studies have been going on in this topic and the optimal reactive power dispatch (ORPD) problem is one of those problems which help us to peruse in the direction towards obtaining a more economic and stable system. Here, the ORPD problem is solved to reduce the real power losses and total voltage deviation (TVD) of few particular standard IEEE bus system. The two objectives are solved individually considering it as a single objective function. In this paper, the ORPD problem is integrated with a photovoltaic (PV) system where the power from the solar energy is added with the power from the existing conventional sources of energy, thus reducing the dependency on fossil fuels to some extent. This study has been done interpret the study of the PV integrated ORPD problem in solving the objective functions. This is mainly intended towards improving the efficiency and enhancing the security of the system. The problem is solved using different algorithms that are developed in the recent past, along with the JAYA algorithm and are tested on IEEE 30 and 57 bus systems to minimize the above mentioned objective functions. The results obtained from the optimization techniques have been compared along with many other techniques reported in the literature to observe the superiority among them.
