Solar PV-D-STATCOM with Three-Phase Grid Interfacing Utilizing MDSC and SLMK-Based Controller

This study illustrates that the employment of a compensator can boost the performance of a solar PV distribution system, when there is volatility in the utility voltage. A two-step control system was used in this investigation. DC- DC converters employ a fuzzy logic controller (FLC) in its first stage to monitor the PV arrays maximum power output. First, the DC voltage is amplified and regulated, and then it is supplied to the voltage source converter (VSC). An open-loop PI controller is utilized so that the DC link voltage may be maintained at a consistent level. The second step is to figure out the DSTATCOM’s reference current. A reference current can be calculated if the quantity of energy produced by solar PV, the amount of electricity required by the loads in the network, and the amount of power lost in the DC links are all known. The SLMK controller calculates the fundamental value of required load current using ADALINE as a reference. When the utility side is pure, generating unit templates under balanced grid conditions comes naturally. However, this is rarely present on the distribution side. Hence, cleaning up dirty grids using multi- delayed signal cancellation (MDSC) yields unit vectors under distorted grid scenarios. This study used MATLAB/Simulink to show how a 32-kW solar photovoltaic array works and to assess the system’s efficiency in both normal testing circumstances and non-linear load situations. To ensure IEEE519 and IEEE 1547 conformance, the MATLAB-simulated system is put through power factor correction (PFC) and harmonics reduction tests in the presence and absence of solar power to replicate utility-side voltage abnormalities.
