Intensive research focusing on developing an optimal design for Hybrid Renewable Power Plants (HRPP) with various types of renewable energy sources (RES) and energy storage systems (ESS) have been developed. The HRPP enables advanced dispatching capability and efficient ancillary services based on a novel renewable energy management system (REMS) tool as shown in Figs. 2 and 3. The HRPP ensures higher flexibility for scheduling RES power generation which paves the way toward 100% renewable energy integration.

The distinguished features of the proposed HRPP can be summarized as follows:

  • HRPP is equipped with intelligent systems and data analytics techniques to identify the failures in response to grid disturbances, and verify the performance in connection with the grid operation and environmental impact.
  • It can be operated in grid-connected mode as well as islanded mode of operation. Consequently, it will enable the black-start capability for efficient system restoration in case of system blackout.
  • HRPP is augmented with REMS tool to enable the grid operator to simulate multiple HRPP dispatching scenarios and to assess participation in scheduling RES power generation over various time horizons in connection with the requirements of economic dispatch, unit commitment and the energy mark operation.
  • HRPP’s flexibility helps to precisely adjust the spinning reserve in case of high penetration of renewable power plants into power grid.
