Tiivistelmä
Industrial microgrids are reshaping their energy sector to meet energy aspects of sustainable development. Carbon emission reduction is the key to achieving the targets and is gaining acceleration with the advancement of renewable energy production, efficient and economic storage technology, and reliable distributed operation of renewable sources. Industries with high carbon emissions are looking for sustainable electrification solutions for their operation reducing dependency on fossil-based fuels. It requires a detailed analysis of sector-specific energy structures for better planning and economic investment to accelerate the process.
Energy management (EM) for dimensioning energy resources to maintain energy balance with the demand is one solution. This thesis was focused on the dimensioning of the energy storage system for the mining industry targeting to achieve fully electrified mining operation. The main idea was to analyze EM with different combinations of the electricity grid and solar photovoltaic (PV) in dimensioning study of storage systems and feasibility analysis of zero operating energy cost of mining operation.
Dimensioning study with EM was performed in different weather conditions and geographic locations to understand their impacts for better electrification planning. The theoretical anticipation reflected on the results, and it was found that the electrified mining operation is possible in different combinations of grid and solar PV. Large variation in storage size was observed in the geographical regions with high solar irradiance fluctuations and less variation in the equatorial regions. The variant nature of solar PV intensifies technical and economic investment challenges on both the storage system and solar PV power plant which leads to uncertainty of zero energy priced mining operations depending only on solar PV generation.
