“…This structure can be managed by more flexible, less expensive, faster, and more reliable control systems instead of other complex systems (e.g., multi-agent, or expert systems) that much of the current literature on smart grid and intelligent computing is proposing. "At least for smart microgrids to supply electricity and also heat using combined heat and power (CHP) as a generation alternative for cases in which a natural disaster strikes, leaving a whole neighbourhood without power, a simpler, more flexible, economical and modular control solution is possible" [32]. Of course, other types of events could also be applied to study different cases dealing with the use of energy under various conditions and circumstances, even considering demand response programs.…”

“…Specifically, it can be described as keeping continuous feedback between energy supply, generation and consumption (and also all other disaggregated values and variables in the microgrid), so as other action algorithms can be easily implemented to achieve certain objectives. These objectives could be a better use of renewable energy resources and DER [32], a wise management of storage systems and, of course, the use of more complicated information provided by the distribution system operator or the utility (which would correspond to the integration of explicit and implicit demand response (DR) programs) [20]. As can be seen, this type of control system has a huge potential to achieve a better integration between a building and the environment (i.e., the power supplier and the renewable energy resources) and also a smarter use of the building (from the point of view of internal conditions as temperature and comfort).…”

“…In both cases, the control system must assure that the required reduction is achieved, when possible. Therefore, this diagram clearly distinguishes between "predictive" and "reactive" control perspectives, which are explained in [32], to keep all the system variables in adequate value ranges. To summarize, in this case study, reactive control is related with direct energy flows management, such as when the battery must be charged or discharged.…”

Nowadays, microgrids are gaining importance in electric power generation and distribution environments due to their flexibility, versatility, scalability and the possibility of supplying ancillary services when connected to the grid. They allow for the customization of electric supply for very different types of consumers. Therefore, a new control model for power and energy management based on homeostaticity of electric power systems (EPS) is presented, which has been already analyzed and approved by ENEL Chile in its developmental stage. ENEL, the largest electric utility in the country, is interested in incorporating smart microgrids in the electricity distribution market, as part of a worldwide policy. Such microgrids are to be installed in buildings serviced by ENEL. To demonstrate the model’s utility, a Simulink model of a real microgrid is used, which is comprised of PV generation, energy storage, an air conditioning (AC) equipment and thermal storage of the building upon which the microgrid is installed. The behavior of every element is simulated, including the dynamic thermal model of the building in order to optimize energy management and power supply versus consumption. The behavior of the whole system is analyzed under different environmental profiles and energy consumption patterns using the proposed homeostaticity system.

“…The relationship among energy users and also the relationship between them the electric utility company with the grid-tied microgrid is vital and must be reinforce with the right incentives. All of these players, the community of users, the electric utility and the grid-tied microgrid together comprise what has been termed a sustainable block in the literature (Yanine, et al 2018)…”

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.

“…Thus homeostasis mechanisms are present in all living organisms, and as such are also applicable to EPS engineering in order to enable and maintain a sustainable performance when they are linked to energy efficiency (EE) and thriftiness. In doing so, both reactive and predictive homeostasis play a substantive role in the engineering of such mechanisms [3,4]. Reactive homeostasis (RH) is an immediate response of the SES to a homeostatic challenge such as energy deprivation, energy shortage or imbalance.…”

For no one is a secret that nowadays electric power distribution systems (EPDS) are being faced with a number of challenges and concerns, which emanate not so much from a shortage of energy supply but from environmental, infrastructural and operational issues. They are required to preserve stability and continuity of operations at any time no matter what, regardless of what may occur in the surroundings. This is the true measure of what sustainable energy systems (SES) are all about and homeostaticity of energy systems seeks just that: to bring about a rapid, effective and efficient state of equilibrium between energy supply and energy expenditure in electric power systems (EPS). The paper presents the theoretical groundwork and a brief description of the model for the operation of SES and their role in energy sustainability, supported by theoretical and empirical results. The concept of homeostaticity in EPDS is explained, along with its role in SES.
