Abstract

This paper studies the main control challenges of hybrid power plant (HPP) integration into weak grids. In this regard, an Electromagnetic Transient (EMT) model of the hierarchical control scheme is simulated in PSCAD software, considering the combination of wind, solar, and battery energy storage for the hybrid power plant. The grid-connected HPP is then studied based on connection to strong and weak grids in order to identify the primary control challenges happening at different control levels. The performance of grid-following controllers will be studied while connecting the HPP to strong and weak grids to clarify the stability criteria based on grid short-circuit ratio (SCR) and reactance-to-resistance (X/R) ratio. Finally, the results of this study are planned to be utilized to further design the HPP control and/or improve the converter control in connection with weak grids.
