With the constant development of hydropower generation and significant progress of HVDC technologies, the variable speed and operation of hydropower plant with HVDC station (unit connection) became technically and commercially feasible. This resulted in a substantial improvement in system efficiency, performance and design flexibility. Further, if the hydro power plant is connected to a DC grid, thus a DC power plant with DC Power generation and DC voltage control is formed effectively and thus a DC power plant will play an important role similar to the conventional AC power plant in an AC grid system. A DC power plant can employ either HVDC Classic station or VSC HVDC station. VSC connection also provides more managed flexibility such as decoupled AC and DC voltage controls and fast electrical emergency braking too. In this review paper, the characteristics and the control principles of the hydropower plant unit connection with HVDC station are introduced. Based on this unit connect, the DC power plant concept is proposed for integration of hydropower into DC grid. The configurations of DC power plant are presented. The advantages of DC power plant and challenges for a practical system are analyzed. It concludes that the DC power plant will have a very attractive prospect for hydropower integration and DC grid application.
