Multi-objective optimization of a simplified factory model acting as a prosumer on the electricity market

This paper presents multi-objective optimization for minimization of both the operating and the investment costs for a hypothetical factory acting as a prosumer on the electricity market. Operating costs are related to the costs of energy supply of factory and investment costs are related to size and the capacity of the available thermal storage, warehouse, as well as PV, power import and power export unit. Operating and investment costs are opposing in the objective function, since costs associated with the increase in the capacity of the structures enable the reduction of the operating costs. The procedure presented in this paper shows the importance of multi- objective optimization and weighting between the two types of costs. Results are presenting the developed Pareto fronts, overall optimum and the annual values of all costs depending on the volatility of market clearing prices and price of fuel. Analysis shows that thermal storage and warehouse capacity have crucial role in offsetting the high prices of the energy supply.
