“…Co-ordinational control schemes were proposed for all central and local controllers in order to operate in various load situations and in situations where there is deviation in energy resource. Stable ac/dc parameters were secured under different conduction modes and also similar works were seen in [21], where the supply from the grid is rectified and connected with the system with a DC busbar so that when the microgrid sources lacks supply still the demand is met. Control strategy of individual solar pv systems and battery storage enable microgrids have been studied in [22], where distributed energy resources are coordinated with distributed generators to implement both active power and reduce the other disturbance effecting the power signals.…”

In this study, a solar photovoltaic microgrid, to sustainable energy and system efficiency, is being studied under different configurations. Solar modules, energy storage devices (battery), power electronics converters are used to validate the desired results. The study of stand-alone to grid-connected systems will be analyzed and tuned for a stable system performance. In the stand-alone tuning, the voltage and the frequency are the key driving parameters to be controlled and evaluated for proper operation of the microgrid. Also, the grid connected configuration will be studied and then both systems will be compiled together using a switching mechanism. The aim is developing a control system that enables the transition between the two configurations. The microgrid is simulated and tested using MATLAB/Simulink platform. The objective is to create a smooth transition of system with control mechanisms in different modes of the microgrid

“…There are many technical and economic advantages related to the implementation of distributed generation in distribution sector that have been widely researched, such as the reduction of active and reactive energy losses, improvement in reliability, reduction of a blackout probability and peak hours' demand reduction; nevertheless, the regulatory aspects have not been covered in depth (Jiayi et al, 2008;ENEL, 2014). However, there is little research related to the social impact regarding the benefits of new policies and regulations that can foster and advance DG in the electric power distribution sector, along with specific urban challenges or local governance factors are likewise not widely analyzed (Gottwalt et al, 2011;Bhavsar et al, 2015;Jain et al, 2017).…”

“…An important area of research for distributed generation has been energy management and differential pricing strategies (Gottwalt et al, 2011;Palensky and Dietrich, 2011;Bhavsar et al, 2015;Cheng et al, 2019), some authors have proposed the establishment of a demand side management (DSM) systems based on an hourly price variation price-structure, as a means to further energy sustainability policies based on energy efficiency and off-peak consumption practices (Wolsink, 2020;Yanine et al, 2022). However, electricity demand peaks are not always of regular occurrence but rather sporadic, and may occur at unforeseen times, usually due to abrupt changes in weather patterns, as well as other environmental or social phenomena, causing a severe strain on the electric power supply services for utilities.…”

Introduction: Integrating renewables in the distribution sector is a rapidly growing reality in many countries, amongst which Chile’s stands out with an increasingly diversifiable electricity matrix. However, incorporating RES into the electricity distribution sector is altogether a steep climb at present, and seen by some as a formidable challenge for utilities. Likewise, the introduction of the Smart Grid agenda in Chile is imposing new challenges to electric utilities, mainly from a regulatory and technical viewpoint. In spite of this, big players like ENEL are moving forward decisively to meet this challenge, together with academia experts.Methods: We model a sustainable energy system in the form of a smart microgrid operated by ENEL Chile comprising a hypothetical community we term a Sustainable Block™ representing an average residential building in Santiago. We then run simulations under different operating scenarios. The model takes into account the most recent innovation in the legal regulatory framework that governs the energy market in Chile ―Law 20,571―which allows for benefits to those that generate and consume part or all of their energy needs while connected to the grid. Thus, the community considers the option of consuming green energy from the microgrid with an energy storage unit to supply electricity to the 60-apartment complex of various sizes. Under this scenario, a set of energy homeostasis strategies that comprise the homeostatic control and energy management systems help balance the electricity supply versus demand.Results: The model proposed comprises a set of energy homeostasis management strategies that have been designed in the power control and energy management system to balance supply and demand while optimizing the availability and use of green energy. Thus, the energy homeostasis model optimizes the microgrid supply while injecting excess power to the grid. In this context, the community residents exhibit different consumption profiles, therefore they may willingly participate of the sustainable energy strategy as prosumers, displaying a thriftier consumption, and enjoying a lower electric bill while using more renewable energy. The model’s energy homeostasis control and energy management system, especially designed for electric power systems, seeks to maintain a dynamic balance between supply and demand and is being currently discussed with ENEL Chile as part of the intelligent control options for the introduction of distributed generation systems tied to the grid, in order to complement their electric power distribution services.Discussion: The model being proposed comprises a community of residents that we term a sustainable block™ representing an average residential building in Santiago, Chile, which aims to take advantage of Law 20,571 in Chile that allows independent electric power generators to benefit by selling electricity to the grid and also allows independent consumers (mostly residential) to generate part or all of their energy needs while connected to the grid. The community may consume electricity from the microgrid with energy storage, operated by the local electric company, supplying electricity to the 60-apartment complex of various sizes. In his regard, just like in the human body where the brain, particularly the hypothalamus, is primarily responsible for the regulation of energy homeostasis, by monitoring changes in the body’s energy state through various mechanisms, the role of energy storage as well as the role of prosumers are the key enabling factors of energy homeostasis and their interaction are highlighted in the overall analysis.

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.
