Abstract

This paper proposes a robust performance analysis for irrigation-based small communities. For this purpose, a green supply system is under consideration with solar photovoltaic (SPV) and Battery storage system (BSS) as the sources of energy. The study is carried out for the Roorkee area situated in the Uttarakhand state of India. The water requirement for the major produced crop in the Roorkee area (wheat) is about 2500m3 to 3500m3 for 4 months per hectare area. Therefore, the SPV system and the battery storage system are sized for the water pumping requirements per hectare. For system sizing, the per-day water requirements are considered. The output voltage of the inverter connected to the SPV system is controlled through the adaptive PID (APID) controller. The single-phase induction motor is connected as a load to the supply system. The solar irradiance corresponds to the considered geographical location (coordinates 29.8543° N, 77.8880° E) is applied for the simulation on MATLAB/SIMULINK®environment. The BSS is considered with a two-day autonomy. The controller’s performance is evaluated and examined through performance indices. For this purpose integral absolute error (IAE), integral square error (ISE), integral time absolute error (ITAE), and integral time square error (ITSE) are obtained. It is observed that the proposed adaptive PID controller shows a comprehensively well transient and steady-state performance compared to the conventional fixed gain PID controller under different system operating conditions.
