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 microgrid concept gives a solution for integration of a large number of distributed generations without causing disruption in the utility network. Microgrids also allow for local control of the distributed generation units and attest to the flexibility to operate autonomously during disturbances in the utility network to increase reliability (Erol-Kantarci, Kantarci, & Mouftah, 2011;Ramirez, Ortega, Bethoux, & Sánchez-Squella, 2014;Trinklein et al, 2014). In addition, the interconnection and networking of groups of microgrids can reduce the energy storage requirements.…”

a b s t r a c tMicrogrids are a key technology to help improve the reliability of electric power systems and increase the integration of renewable energy sources. Interconnection and networking of smaller microgrids into larger systems have potential for even further improvements. This paper presents a novel approach to a distributed droop control and energy storage in networked dc microgrids. Distributed control is necessary to prevent single points of failure along with flexibility and adaptability to changing energy resources. The results show that systems with random sources and fast update rates, a networked microgrid structure can minimize required energy storage requirements.

“…The Power Flow Controllers (PFC) 1 are also called Current Flow Controllers (Balasubramaniam et al, 2019), Dynamic Energy Routers (Ramirez et al, 2014) or Smart Nodes (Zafeiratou et al, 2018). They are necessary power electronic devices in the context of meshed grids to manage the distribution of the power between the multiple paths and prevent the overloading of some lines.…”

“…The control of shunt-connected DC PFCs has been addressed in a few papers. Among them, recall a multiterminal PFC (Takahashi et al, 2015) improved in (Natori et al, 2018), a similar three-branch PFC in (Ramirez et al, 2014) and a PFC made of two separate Split-PI converters (Barara et al, 2017). The main shortcomings of (Takahashi et al, 2015;Natori et al, 2018;Barara et al, 2017) are the absence of dynamic model, proof of stability and proof of robustness.…”

“…The experiments are conducted by imposing this voltage using an auxiliary power supply. In (Ramirez et al, 2014), different control strategies are proposed: a PI controller and an approximated feedback linearisation controller. These strategies are based on current control, with a current reference computed by dividing the power reference by the line voltage.…”
