This work proposes a method of energy management of a university campus, with a photovoltaic solar generation source and a energy storage system, which are connected to the main grid. The developed method aims to minimize the purchase of energy from the external grid using the Simulated Annealing optimization method. It is considered in the simulations variable energy tariffs according to the period of the day applied by the local utility. The obtained results were satisfactory, since the applied management scheme managed to reduce energy consumption significantly throughout the day, taking advantage of the energy stored at cheaper tariff schedules and greater availability of solar generation at peak times, making a minimum daily cost while it reaches the constraints associated with the problem. The obtained results showed the applicability of the optimization method, through the determination of operating points of the battery bank that maximized the use of available resources

Sistema de gerenciamento de energia como ferramenta de eficiência energética na indústria
(Universidade Federal do Pará, 2015-02-24) SOARES, Gerdson Tanaka; TOSTES, Maria Emília de Lima; http://lattes.cnpq.br/4197618044519148
This work shows the power management as a management tool for Energy Efficiency in Industry by the side of the energy use in the production process of an industry. An important action in the process is to build the interactivity between users and the electricity. It is proposed the implementation of metering devices, control and diagnosis in order to get a better the use of electricity, and with the acquisition of data from these devices allow management to reduce energy consumption and to make the management aiming at energy efficiency. Presents the results of the system proposed in areas with central refrigerating of a plastic products industry to serve the food industry. The present study, has also applied a methodology used as measurement and verification (M & V) to assess the actual percentage of savings achieved after the implementation of energy efficiency measures.
