Modelo matemático de distribuição de água para otimização de custos elétricos

Abstract

Nowadays, one of the great concerns of society is the environment and the impact of human actions on it. In this context, one of the most precious assets of the environment is water, which is crucial for human survival. One main means of water access in the urban environment is through water treatment plants that transpose the stored water to distribute it to the population using pumps and pipelines. Electricity cost is currently the largest and the most important expense of several sanitation companies when treating water. This project develops a mathematical model in Mixed Integer Linear Programming that represents a real water transposition system of a water treatment company. This model is compared with real operation data for validation and possible application as a tool for the decision-making process. In this sense, it seeks to reduce the energy costs of the pumping system by shutting down the pumps at peak and low demand times. The pressures generated by the water distribution system are also an essential variable for the sanitation companies. It is necessary to keep their level in a limited range; therefore, the output values of the model should generate bounded pressures checked by an algorithm also developed in the project.
