A multi-area load frequency control system for an interconnected hybrid power network, and a method to control a load frequency. The load frequency control system includes multiple dispersed load frequency control systems located in a plurality of areas, having a point of common coupling (PCC). Each load frequency control system also has a hydrogen/bromine redox flow battery (H2/Br2-RFB) connected to the PCC to mitigate a frequency fluctuation during a load perturbation. Each load frequency control system also has a renewable energy source and a power plant connected to the PCC. Each load frequency control system further comprises a load frequency controller connected to the power plant. The load frequency controller includes a processor configured to execute a program instruction, a tilt-based fractional order proportional integral (TFOPI), and a model predictive controller (MPC). The load frequency control systems are communicatively connected to each other.

Control system for interconnected hybrid power network

A device, method, and non-transitory computer readable medium for a finite-time sliding mode maximum power point tracking (MPPT) control system for a photovoltaic (PV) array includes a PV array configured to generate a current I, a pulse width modulator (PWM) connected to receive the current Iand a voltage. The PWM is configured to execute a perturb and observe (P&O) algorithm and generate a maximum power point signal. The maximum power point signal is configured to modulate DC voltage Vaccording to a duty cycle D defined by the P&O algorithm. The MPPT control system includes a finite time sliding mode controller (FTSMC) configured to receive the Iand a voltage and generate a reactive power control signal U. The FTSMC includes a particle swarm optimization to determine and apply optimum gain parameters to FTSMC to generate reactive power control signal Uand minimize voltage error signals for each phase.

Methods and systems for solar photovoltaic automatic voltage regulation under extreme weather conditions

A device and method for managing power transmission to a power grid from a Hybrid Grid Connected System (HGCS) is presented. The HGCS includes a plurality of energy resources, including of solar photovoltaic cells (PV), wind power generation, a battery energy storage system (BESS) and a fuel cell system paired with an electrolyzer. Energy sources are connected by a DC-link to a power electronic converter which supplies power to the power grid. A controller is configured to calculate the total power, maximize transmission of power to the power grid from the primary sources, supply the net power to the power grid from the fuel cell system and use the power generated by the PV system and the wind power system for charging the BESS and powering the electrolyzer system based on the relative state of charge of the BESS and the voltage of the DC-link.
