Abstract
The intermittency and variability of solar resources pose significant challenges to ensuring an uninterrupted electricity supply in power systems with high photovoltaic (PV) penetration. Firm renewable power generation research aims to provide a cost-effective solution for a firm, dispatchable power supply from variable renewable energy sources, using various firm power enablers, including overbuilding and proactive curtailment, blending of wind and solar energy, and energy storage. However, most related studies focus on achieving 95–100% firm coverage of power demand, and therefore, present only visions for decades ahead without actionable short-term suggestions. This study extends the concept of firm power generation with a new dimension by optimizing power supply for different renewable coverage ratios and thus enabling the assessment of a complete pathway of renewable transition. The added insights of this new approach are demonstrated through a case study of a firm renewable power supply for Hungary based on solar PV, wind turbines, and three energy storage systems, namely lithium-ion (Li-ion) and sodium-sulfur (NaS) batteries, and hydrogen. The sizing and operation of the hybrid renewable energy system are optimized using linear programming for all renewable coverage levels from 1% to 100% in 1% increments. The results reveal the optimal installed capacities of all components and the levelized cost of electricity for the renewable power supply as functions of the renewable coverage ratio, which can also support stakeholders in making energy strategy decisions towards the decarbonization of the electricity supply.
