Abstract
In today’s global industrial environment, the need for sustainable, efficient, and energy-saving solutions for energy supply is more significant than ever and every enterprise that has adopted the policy of a green and low-carbon economy must seek such solutions. Enterprises must analyze their largest energy consumers and look for alternative options for generating and using “green energy”. Photovoltaic systems are among the most common solutions, but their dependence on weather conditions requires integration with energy storage systems. This report presents a model and analysis of an integrated hybrid photovoltaic system with battery storage, designed to provide electricity for energy-intensive production processes under the conditions of the Bulgarian climate and electricity market.
