Conception d’un stockage d’énergie éolienne pour une entreprise minière isolée du réseau : faisabilité du stockage par pompage hydraulique

Abstract

This thesis studies the technical and economic feasibility of integrating intermittent renewable energy into the Raglan Mine's carbon grid. The objective is to design a wind farm and a pumped-hydro storage system to reduce diesel consumption and associated GHG emissions. For this purpose, the operation and consumption of both electricity and heat networks are detailed, providing the energy needs of the mine. To meet these needs, both a wind farm and a PHS plant are sized. The first design uses historical data from the two existing units while the second relies on the search for potential sites. A MATLAB algorithm is implemented to simulate the paring of thermal generators, wind turbines and the PHS plant, providing the grid performances. By establishing technical and economic feasibility indexes, the viability of the different simulations is assessed. The results indicate that there are three potential sites that can accommodate a PHS plant while ensuring the profitability of the project. The most convincing simulation estimates a payback in 2033 with a final balance of over CAD 100 million in 2037. In particular, this results in a reduction in annual GHG emissions from 105,500 to 37,000
