Adequacy assessment of renewables-dominated power systems with large-scale energy storage

Abstract

Most research relevant to power system adequacy with large-scale penetration of variable renewable energy sources (RES), including assessment of RES capacity credit, has focused on relatively small penetration levels, up to some 30%. However, RES contribution to supply peak demand with much higher shares of renewable energy, and even close to 100%, has been less studied, and the actual feasibility of such a RES-dominated system in terms of preserving a certain level of system reliability is as yet unclear. In this work, a Monte Carlo simulation model is adopted to quantify the system adequacy level. The availability curves of conventional generation units are simulated based on the state-dur..
