The Influence of Hybrid Renewable Energy Source Plant Composition on Transmission System Stability.

Hybrid power plants consisting of renewable generation and storage technologies have been seen as a solution for providing stable power output from renewable energy sources. Given the installation capacity of renewable generation and storage units, their impact on power system operation can no longer be neglected. The paper analyzes the influence of a hybrid renewable energy source plant on small disturbance, transient and voltage transmission system stability on the basis of a representative set of power production profiles of the plant. The patterns in the behavior of the whole plant in the considered system stability studies are identified, which is a first step in developing dynamic equivalent models of the hybrid power plant for those types of system stability.
