Floating Photovoltaic Systems Coupled with Pumped Hydroplants under Day-Ahead Electricity Market Conditions: Parametric Analysis

The intermittent nature of the solar resource together with fluctuating energy demand day-ahead electricity market requires use efficient long-term storage systems. pumped hydroelectric (PHS) power plant has demonstrated its technical and commercial viability as a large-scale technology. objective this paper is to analyse parameters that influence mode operation in conjunction floating photovoltaic (FPV) under conditions. This work proposes analysis two parameters: size FPV total process efficiency PHS plant. Five sizes are analysed: 50% (S1), 100% (S2), 150% (S3), 350% (S4) 450% (S5) values parameter analysed follows: 0.77 for old plants, 0.85 more modern plants. number daily operating hours 4 h. These h correspond highest prices on market. framework study Iberian Alto Rabagão dam (Portugal). Different scenarios considered identify optimal Based measured data climatic conditions, an algorithm designed estimate production different If 0.85, joint both plants S2 S3 yields slightly higher economic benefit than independent operation. 0.77, there always mode, irrespective However, uncertainty estimation can lead mode. Increasing above per day decreases regardless As increases, decreases. results obtained reveal coupling systems cost-effective reliable alternative provide sustainable supply security In summary, purpose facilitate decision making case studies allow find answer following practical questions: What does have be order better adapted market? appropriate plants? changing turbine pump plant? Finally, how installation affect water volume upper reservoir Knowledge these questions will design
