“…MGs must be robust to control the voltage, frequency and protect the main grid and the loads connected to the various faults [8,9,10]. MGs also facilitate the administration and re-synchronization of the demand side.…”

“…The combination between the AC and DC MG configurations has resulted in the concept of AC/DC HMGs (see Figure 2) and proposes a better approach because it combines the main advantages of the AC and DC MGs [10]. Future trends show that features such as scalability, modeling, design, and control structures require further investigation to achieve integration of HMGs into the main grid [7,15,23].…”

This paper presents a new hybrid strategy which allows the dynamic identification of AC/DC microgrids (MG) by using algorithms such as Auto-Regressive with exogenous inputs (ARX) and Petri Nets (PN). The proposed strategy demonstrated in this study serves to obtain a dynamic model of the DC MG in isolated or connected modes. Given the non-linear nature of the system under study, the methodology divides the whole system in a bank of linearized models at different stable operating points, coordinated by a PN state machine. The bank of models obtained in state space, together with an adequate selection of models, can capture and reflect the nonlinear dynamic properties of the AD/DC MGs and the different systems that it composes. The performance of the proposed algorithm has been tested using the Matlab/Simulink simulation platform.

“…Distributed generation (DG) sources constituted by new renewable and non-renewable energy sources such as micro-turbines (MT), photovoltaic systems (PV), fuel cells (FC), and wind generators systems (WGS), propose a more efficient and cleaner technology which in turn are able to supply the growing demand for electricity in interconnected and islanded communities [ 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 ].…”

Microgrids (MG) treat local energy supply issues effectively and from a point of view of the distribution grid, may be a power supply or virtual load. Despite holding a myriad of benefits, MGs also bear a set of challenges, including a higher fault rate. Currently, many articles focus on control techniques; however, little has been written about the techniques of control, hierarchical control, and fault-tolerant control (FTC) applied to MGs, which is the motive of this bibliographic revision on control systems. A brief comparison of the different approaches in the field of present-day research is carried out primarily addressing hierarchical control and fault tolerance. The objective of this investigation is to attract the interest of researchers to the field of control and fault tolerance applied to MGs, such as: modeling, testbed, benchmark systems, control and hierarchical control strategies, fault diagnosis and FTC.

“…There is also the disadvantage of the lack of rolling stock due to its limited capacity to expand the system, which is, somehow, to be solved with renewable generation. With the limitation of the generation, there is a poor response to demand demands, which influences load disconnection events (Carrión & Ortiz, 2013;Shafiullah, Alsharif, Hossain & Ahsan, 2014).…”

Alternative Under Frecuency Load Disconection Methodology Based on Semi-Adaptative Model

Stability analysis in electrical power systems is based on the study in dynamic state of the voltage and frequency, since at the moment that there is some contingency it fluctuates drastically due to the primary and secondary controls of the voltage and frequency to the power systems that act on the generators. In order to solve the possible stability problems that may arise in power systems, various techniques have been developed that act on the generating machines for their protection as well as on the loads for the power cut. The present investigation proposes an alternative methodology for load disconnection by low frequency as an option to save the power system from a possible blackout due to instability due to a fall in the frequency, managing to improve the results affected by other improved techniques, the frequency change range, frequency deviation and the effects of demand disconnection. The proposed methodology was tested in the IEEE 14 bus system.
