In recent times, the power demand has been increased worldwide due to industrialization and urbanization using Plug-in Hybrid Electric Vehicles (PHEVs). To improve Harmonic Distortion, a Hybrid Solar and Small Hydro (HSSH) based hybrid form of the renewable energy system has been developed. However, the high penetration of varying nonlinear PHEVs loads on the grid system can impact the system's performance in terms of power loss, voltage fluctuations, power quality, and harmonic distortion. In this article, Kalman Decoupled Harmonic Power Flow (KDHPF) technique is proposed primarily to calculate the harmonic current in the grid system. Consequently, the Bessel Filter Sallen Key (BFSK) and Multiobjective Firefly Algorithm (MOFA) are projected to control the bidirectional converter's voltage and current to improve the quality of power in the coordinated grid system. The power loss, error rate, and Total Harmonic Distortion (THD) have been optimized by the MOFA optimization method. The implementation of this work is done in the MATLAB/Simulink platform. Moreover, the observed simulation results are compared with various existing techniques for validating the efficiency of the proposed method in terms of reduced 3.5% of THD and 0.000142 MW of power loss. The consequences proved that the projected grid coordinated system had achieved the finest performance under diverse cases.

<p>Small hydro systems play a major role in meeting power requirements of remote, isolated, hilly areas in a decentralized manner by tapping water streams, rivulets and canals of small discharge. Small hydroelectric system captures the energy in flowing water and converts it to electricity.</p>Of all the non-conventional renewable energy sources, small hydro stands first as it is more resourceful, reduces system  losses, environment friendly, non-consumptive and source is renewable due to their enormous advantages over large hydro and other power plants, lot of small hydro-power plants have come up across the world to meet the ever increasing demand of electrical energy. Lowering the high initial cost of the small hydro-power plants and its popularization is today’s challenges. This paper describes basic techniques design of the small hydro-power development.
