Renewable Sources Complementarity

Abstract

AbstractThe presence of renewable sources in modern power grids is a means of supplying greener and more sustainable energy to the final customers. However, this inherent variability of energy sources requires the addition of resources for grid flexibility. This variability depends on the availability of the primary energy source, which varies in time and space. However, it is possible to take advantage of an energy mix due to the complementarity effect. This chapter aims to review the concepts regarding the complementarity of renewable energy sources, by describing some of the existing indexes from the literature so that they can be evaluated in different time and space scales. Larger network and geography are considered here. The reason being, when the active network concept is expanded, additional techniques and technologies are required to broaden the scope of active networks for provincial, state-wise and/or country-wide active networks. In this sense, complementarity becomes crucial for different microgrids working in connected modes. This chapter provides this bridge.KeywordsComplementarityVariabilityRenewable sources of energy
