A comprehensive review about the control architecture of co-located utility-scale hybrid power plants: state-of-the-art and future directions

In recent years, there has been a growing interest in reducing greenhouse gas emissions by integrating new technologies into energy delivery systems. Hybrid power plants (HPPs) have become popular for their potential to add market value benefits. The harmonization of diverse dynamic technologies and intricate interactions within an HPP to meet mandatory grid compliance presents a complex challenge that necessitates further investigation. Before developing the control functions, it is necessary to define the control architecture. Thus, the interactions between the HPP control functions need to be studied and considered carefully. This study aims to provide a literature review of control architectures for co-located utility-scale hybrid power plants. It will discuss the existing approach, which is centralized hierarchical control, along with its advantages and limitations. Additionally, this review paper will identify potential future research directions for developing HPP control architectures, taking into account the technical challenges and emerging markets in the renewable energy sector.
