SyRG-PV-BES Based Standalone Microgrid Using Appoximate Multipliers Based Adaptive Control

To maximize practical reliability and ability of the distributed generations (DGs), this paper managed to design, control and hardware authentication of novel adaptive algorithm. The proposed approximate multiplier least mean square (AMLMS) control algorithm for an off-grid voltage source converter (VSC) system is effective for reduction of power disturbances without disturbing the power quality (PQ). Moreover, the VSC control algorithm focuses on reduction of complexity of LMS by adding multipliers in the finite impulse response (FIR) filter and in updating coefficient in circuitry. Moreover, a synchronous reluctance generator (SyRG) based pico-hydropower generation at the AC side is used because of its reliability, and cost-effectiveness than other brushless generators. The VSC control is projected for islanded microgrid comprising of photovoltaic (PV) array, and a bidirectional DC-DC converter (BDC) at the DC side. The BDC with a storage battery, maintains the optimal power flow to provide the power equilibrium between load and sources through DC bus voltage regulation. Moreover, BDC mitigates the second harmonic current from the battery charging and discharging current. Experiment results ensure the validation and effectiveness of proposed controller.
