Nyström Minimum Kernel Risk-Sensitive Loss Based Seamless Control of Grid-Tied PV-Hybrid Energy Storage System

This paper presents Nyström minimum kernel risk-sensitive loss (NysMKRSL) based control of a three-phase four-wire grid-tied dual-stage PV-hybrid energy storage system, under varying conditions such as irradiation variation, unbalanced load, and abnormal grid voltage. The Voltage Source Converter (VSC) enables the system to perform multifunctional operations reactive power compensation, load balancing, harmonics elimination while maintaining Unity Power Factor (UPF). proposed VSC delivers more accurate weights with fewer oscillations, hence reducing overall losses providing better stability system. seamless Hybrid Energy Storage System (HESS) facilitates system’s isolated operation. HESS includes battery, fuel cell, ultra-capacitor accomplish peak shaving, managing disturbances sudden prolonged nature occurring due unbalancing DC link voltage is regulated by tuning PI controller gains utilizing Salp Swarm Optimization (SSO) algorithm stabilize deviation from reference voltage, during various simulated dynamic conditions. optimized bus generates component current, which further enhances performance control. presented was in MATLAB 2016a environment performed satisfactorily per IEEE 519 standards.
