The power generated by wind and solar energy fluctuates. Electrical measurements based on switching activity determine the performance of the wind turbine and, in turn, the power quality. This power quality problem is attributed to wind turbines installed on the grid. The proposed solution uses a nonlinear adaptive sliding mode strategy. Compare the proposed NASMC performance with conventional controllers to improve power at rated speed. Although many different models have been proposed for new applications, STATCOM is connected to the battery energy storage system at the common node, thereby reducing power quality issues. In the centralization of power system modules, to simulate grid-connected wind energy photovoltaic systems, and uses the STATCOM control scheme to improve power quality. In the solution proposed here, it can reuse the main power from the load and the reactive power demand of the induction generator. © 2020 Elsevier B.V., All rights reserved.
