“…If the power generated within the MG is more than needed, it will transfer power to the upper grid. Keeping this in mind, many research papers present strategies for grid-connected, islanded and transition operation [3,8,25,26].…”

“…In the former case, it is required an ac/dc converter that fixes the voltage in a master-slave operation. In the last case, the control of the DC-MG must be coordinated in a hierarchical architecture that maintains the voltage under a limited range [9].…”

“…The primary control brings the system to a stable operation using a droop control strategy, while the secondary control ensures system reaches the reference voltage, and the tertiary control defines the reference considering economic, and/or environmental objectives [9]. Primary control is usually local while secondary/tertiary can be designed taking into account communications among the converters.…”

This paper presents a Passivity Based Control (PBC) for a dc microgrid. PBC is commonly used in electrical systems such as power electronics converters and electric machines, but there are few applications in microgrids operating in island mode. PBC is based on properties of passive systems and energy exchange between subsystems. The proposed strategy performs primary and secondary control of the hierarchical architecture. Local communications and measurements are needed at the nodes where dc/dc converters are placed. Simulation studies are performed in MATLAB to validate the control in a realistic test system composed of renewable energies sources, loads and energy storage units. Results show that the proposed control ensures stability and fast response of the dc-bus voltage under different operating conditions. RESUMEN: Este artículo presenta un Control Basado en Pasividad (CBP) de una microrred DC.El CBP se utiliza conmunmente en sistemas eléctricos como convertidores electrónicos de potencia y máquinas eléctricas, pero hay pocas aplicaciones en microrredes que operan en forma aislada. El CBP se fundamenta en las propiedades de los sistemas pasivos y en el intercambio de energía entre subsistemas. La estrategia propuesta desarrolla control primario y secundario de la arquitectura de control jerárquico. Son necesarias comunicaciones locales y mediciones en los nodos donde se ubican convertidores dc/dc. Estudios de simulación son realizados en MATLAB para validar el control en un sistema de prueba real compuesto por fuentes de energía renovables, cargas y unidades de almacenamiento de energía. Los resultados muestran que el control propuesto garantiza estabilidad y rápida respuesta del voltaje del bus dc bajo diferentes condiciones de operación.

“…The problems associated with AC microgrids such as synchronization of generators, reactive power and line unbalances, as well as their energy losses when converting to DC, also favor the move to DC microgrids [1][2][3]. Comparing to AC microgrids, it is easier to integrate the renewable energy sources (RES) and storage systems in DC microgrids because of elimination of multiple power conversion stages, especially for some DC sources like PV, fuel cell, battery storage, electric vehicle, super capacitor, etc.…”

A Feed-Forward Control Realizing Fast Response for Three-Branch Interleaved DC-DC Converter in DC Microgrid

et al. 2016

It is a common practice for storage batteries to be connected to DC microgrid buses through DC-DC converters for voltage support on islanded operation mode. A feed-forward control based dual-loop constant voltage PI control for three-branch interleaved DC-DC converters (TIDC) is proposed for storage batteries in DC microgrids. The working principle of TIDC is analyzed, and the factors influencing the response rate based on the dual-loop constant voltage control for TIDC are discussed, and then the method of feed-forward control for TIDC is studied to improve the response rate for load changing. A prototype of the TIDC is developed and an experimental platform is built. The experiment results show that DC bus voltage sags or swells caused by load changing can be reduced and the time for voltage recovery can be decreased significantly with the proposed feed-forward control.
