Optimize the cost of paying for electricity in the water supply system by using accumulating tanks

Abstract

The article considers the method of optimizing the pumps in the water supply system of the first water rise station in the zones of the day, where there is a different system of payment for electric energy. To assess the regulatory capacity of pumps on a temporary parameter, the authors of the article propose to use existing water tanks in the water supply system, which act as a buffer, smoothing the unevenness of water consumption. The studies have revealed that the comprehensive optimization of pumps on the criterion of minimizing specific electricity consumption by lifting water and optimizing the operation of pumps in the zones of the day allows to significantly improve energy efficiency and reduce the cost of extraction and transportation of water to the consumer. In the article, the authors examine an algorithm that allows us to assess the economic potential of pump regulation in the real-world conditions of the system.
