Abstract
Today’s power generation and distribution industry is being faced with a
number of issues, from violent weather phenomena to earthquakes, fires and
landslides; including acts of arson, terrorism and vandalism, all of which pose
serious concerns for the sustainability of the distribution and supply of
electricity. Electric utilities like ENEL are cognizant of this fact and know
they must take action. Moreover, they are required by law to be prepared and
act proactively to prevent service disruption, by responding to such challenges
rapidly and effectively so as to preserve stability and continuity of operation.
Homeostaticity of energy systems seeks just that: to bring about a rapid,
effective and efficient state of equilibrium between energy supply and
expenditure at all times, whatever the circumstances, to preserve stability of
systems operation. The paper presents a prescriptive energy homeostaticity
model being considered by ENEL as a means to further the incorporation of
renewables in the electricity generation and distribution industry. The aim is
to enhance control and energy management systems in distributed generation
installations tied to the grid for urban and rural communities, in order to
complement and diversify their electric power distribution services. The
theoretical groundwork underlying the subject as well as other relevant
contextual factors are also discussed and simulation results are presented
under different tariff scenarios, and energy storage alternatives, in order to
compare the proposed model with the actual case. Energy storage (ES) is
found to be of paramount importance in the overall analysis of the results as it
enhances and reinforces thriftiness on energy consumption.
