Modeling of energy consumption in foundries by integrating renewable energy sources: Kolhapur foundry sector

Abstract

Energy is a vital issue in the discussion of sustainable development. Increasing demand and scarce availability of resources with limited environmental impact are outlining aspects of developing the energy model. This paper reveals a grid–solar–wind energy system for energy modeling. Mathematical model has been developed which relies on two important factors of industrial energy consumption: energy cost and CO2 emission. This model is validated by using data from foundry cluster, Kolhapur industrial sector. Load assessment and resource assessment in Kolhapur area have been done. Constraints required for programming are obtained from HOMER software. Genetic algorithm multi-objective optimization is carried out by using MATLAB to solve these two conflicting objectives. Pareto optimal solution gives no judgment about equality of distribution in different energy sources. But it gives a set of optimal values which satisfies the two objectives: minimization of energy cost and minimization of CO2 emission. This developed modeling will help to do proper integration of largely available renewable sources such as solar and wind energy sources.
