RESUMENLas microrredes eléctricas son consideradas una alternativa para la generación y distribución de electricidad en entornos rurales alejados de la red de distribución principal, y necesitan nuevas estrategias de intercambio de datos entre las cargas y generadores distribuidos, según la estratégia de control elegido para la microrred, con el objetivo de entregar energía eléctrica de buena calidad. En el presente artículo se realiza el análisis de los parámetros de un algoritmo de encaminamiento por demanda, aplicado a una red de sensores inalámbricos, para el intercambio de datos de control entre los elementos que componen una microrred eléctrica aislada, con el fin de identificar y reconfigurar la topología de red para el esquema de control elegido de la microrred aprovechando los procesos de descubrimiento y búsqueda de rutas del protocolo.Palabras Clave: AODV, Microrred, Redes de sensores inalámbricos. ABSTRACTMicrogrids are considered an alternative for generation and distribution of electricity in rural areas far from the main electrical grid, and new strategies for data exchange among distributed generators are needed, depending on the control scheme chosen for the microgrid, with the purpose of delivering good quality power. In this article, the parameters of an on demand routing algorithm are analyzed, applied to a wireless sensor network, for control data exchange among all islanded microgrid generators, in order to identify and reconfigure the chosen network topology scheme, for the microgrid, taking advantage of the protocol's discovery and route search processes.

“…Determining how to effectively tackle the problem of the harmonic currents in the wide-band frequency domain caused by the distributed and clustered inverters has been gained much attention in the flied of the power quality of the microgrid operating in both islanded and grid-connected mode [58]. The most significant problems in the islanded mode are how to effectively realize power sharing among parallel inverters, also reduce the fundamental and harmonic circulating currents among them.…”

This paper investigates the stability of LCL-filtered grid-connected inverters with capacitor current feedback (CCF) active damping. The impact of time delays in the digital controller on active damping and its equivalent virtual impedance is analyzed. The inherent relationship between these time delays and stability is illustrated. Specially, a critical value of the CCF active damping coefficient k damp_c is proposed to define three distinct regions of stability evaluation. If k damp_c [ 0, a sufficient but smaller damping coefficient (k damp \ k damp_c ) is recommended as optimum damping solution; if k damp_c = 0, system will be unstable irrespective of active damping; and if k damp_c \ 0, active damping is not necessary to design a stable system. Necessary conditions to ensure stability are identified; guidelines for controller design are then presented to optimize the performance of active damping and dynamic response. Simulation and experimental results confirm the presented analysis.
