Design and Frequency Control of Small Scale Photovoltaic Hydro Pumped Storage System

The world is directing its efforts towards achieving 100% renewable power generation. This paper presents design and frequency control of small scale photovoltaic hydro pumped storage system. The main problem of small scale hydro pumped storage system is its low efficiency. In this research to improve the performance of small scale hydro pumped storage system, a dual usage for the system and an intellgient control method are proposed. The storage tank design calculations are performed for traditional water usage. The traditional water usage includes covering water consumption, covering time needed for the disinfection, covering the requirements in emergency cases and firefighting demand. The calculations are carried out to predict the generated power for each design case. The frequency control is performed by using Non linear PID controller / PID controller and neural network at different operating conditions. The simulation and optimization are performed using MATLAB / SIMULINK 2017a.
