“…The active and reactive power exchange between the MG and the grid is managed by an optimization strategy (Level 3) that minimizes or maximizes an objective function [9], [20]. Such a function can be the maximization of the MG income or the minimization of the microgrid energy cost or fuel consumption, depending on the users' priorities.…”

Types of inverters and topologies for microgrid applications ABSTRACTInverters are the key actuator in the control of AC microgrids, since they manage the power flows of both the generators and energy storage devices. In general, there are three types of inverters depending on the control strategy: grid feeding inverters, grid forming inverters and grid supporting inverters. Those inverters can be implemented with different hardware topologies, each one of them with advantages and disadvantages. This paper presents a synthesis of the inverter topologies widely used in AC microgrids. Moreover, this paper also describes the inverters architectures and main control strategies.

“…Para garantizar un desacople de potencia y una relación P-f y Q-V adecuados, se utiliza una impedancia virtual en cada inversor, que consiste en un lazo de re-alimentación de corriente multiplicado por el valor de la impedancia virtual [8], [9], [10].…”

MojicaNava, "Mejoras de la regulación de frecuencia utilizando el aumento de inercia de microrredes interconectadas", UIS Ingenierías, vol. 16, no. RESUMENEl control por pendiente garantiza la regulación de frecuencia y el reparto de potencia activa entre los inversores de una microrred aislada, sin embargo, introduce desviaciones respecto a la frecuencia de referencia. Cuando un generador adicional basado en inversores se conecta a una microrred, se reduce la desviación en frecuencia y se aumenta la capacidad de potencia de todo el sistema; de igual modo, la interconexión entre microrredes en modo isla tiene el mismo efecto. El control por pendiente ha mostrado ser efectivo en microrredes basadas en inversores, sin embargo, cuando uno o más generadores sincrónicos se conectan directamente a la microrred, cambian las condiciones de dicho control. Para analizar que ocurre cuando se interconectan microrredes en modo isla se analizan los casos cuando ambas microrredes constan únicamente de inversores, y cuando una microrred o ambas tienen al menos un generador sincrónico. De esta manera, los resultados de simulación presentados demuestran las mejoras de la regulación de frecuencia utilizando el aumento de inercia de microrredes interconectadas.PALABRAS CLAVE: Microrred, Control por pendiente, Frecuencia, Interconexión, Generador sincrónico, Regulación. ABSTRACTDroop control guarantees frequency regulation and power sharing among the inverters in an isdated microgrid, however, frequency deviations are introduced with respect to reference values. When an aditional distributed generator based on inverters is connected to the microgrid, such deviations are reduced and the power capacity of the system is improved; same way happens when microgrids are interconnected. Droop control has shown to be effective in inverter based microgrids, however, when one or more synchronous generators are directly connected to the microgrid the conditions of the controller change. To analaize what happen when islanded microgrids are interconected different cases are considered: first when both microgrid are based only in inverters, and other case in which one microgrid has at least one synchronous generator. In this way, the simulation results show the regulation frequency improvements using the inertia increase of networked microgrids.

“…On the other hand, microgrids planning involves many economic and technical variables into a complex decisionmaking process. Given the importance of this topic, there are many studies addressing the planning process as an optimization problem [3]. Usually, the objective function is proposed in terms of implementation and operation costs, and the constraints are the technical limitations of generators or storage systems.…”

Microgrids adoption around all world is increasing with different aims as to integrate renewable generation, providing energy to rural zones, reducing CO2 emissions, or simply as an alternative for energy independence. However, the planning and operation of microgrids can be a challenging task because it involves many economical, technical, environmental aspects. This work presents a methodology for planning and validating a grid-connected microgrid using two well-known software that facilitates the design. The planning process is performed in HOMER Pro to size and select appropriate generation sources, while the possible implementation on a real distribution network is validated in DigSILENT. Numerical results show the optimal sizing process of a grid-connected microgrid for a university campus based on real data and the technical validation based on Colombian regulatory aspects.
