SOFTWARE AND HARDWARE FOR RATIONAL USE OF ENERGY

MODCAE – Computer program for simulating electric water heating loads in distribution networks. It uses physically-based load models to account for the payback effect of this type of thermostat controlled loads when they are switched on after an interruption of supply. This is adequate to capture the effects of load dispatch procedures in distribution network management. Model output consists of load diagrams. Loads are organized in groups and their respective diagrams are mostly influenced by water consumption patterns, which are programmable.

ACORCE – Software package for helping consultants and energy managers to evaluate energy conservation opportunities and cost-saving measures related to electric energy use. It allows capturing and processing of load diagrams collected with dataloggers during energy audits. It also allows the interactive definition of the tariff system to be used in economic analyses.

PIAC – Interactive information counter, based on a data concentrator of electricity, natural gas and water consumption values within a building. It computes both remote and local pollutant emissions due to the use of resources. Consumption values are constantly monitored and stored in a database. Interactivity is provided by a computer screen and a trackball, allowing visualization of diagrams and accumulated values of emissions and consumption, as well as allowing comparisons on annual, monthly and weekly bases. (Can be demonstrated at DEE-FCTUC).

SINCE – Database for storing energy consumption, electric load diagrams and other relevant data originated in load research studies. Each load diagram in the database is related to other information, as for example on the corresponding equipment or premise, on the proprietor, and so on, allowing several different query specifications for different purposes.
