“…This will decrease the number of failures, increasing mean time between failures (MTBF). This will increase the reliability [16] of the system. So it is obvious that above two tasks require two feedback loops.…”

High power rating and robustness of AC drive has made Induction motor based motion control a preferable choice in the industrial applications. This paper embarks on the issues of bidirectional power conversion, regenerative braking and energy storage. A simplified and cost effective method of three phase inverter fed induction motor drive capable of regenerative energy storage is discussed. This method is very useful for Hybrid Electric Vehicles, Traction Drive and hoist drive applications. The proposed method is focused on smooth control and energy efficiency of AC drive systems. A simulation model has been developed for the analysis of system dynamics and power flow. Also a microcontroller based experimental setup for one kilowatt induction motor is proposed. Further the obtained simulation results are validated and compared with the experimental results.

“…In recent years, countries have rapidly developed clean renewable energy, and the proportion of installed capacity of photovoltaic (PV) power systems in the power system has been rising. Since the output power of the PV power system changes with the weather change, the grid connection of a large-scale PV power system will affect the stability and reliability of power grid operation [1][2][3][4][5]. The installation of the battery energy storage station (BESS) in the grid-connected PV power system to stabilize their output power fluctuations.…”

Aiming at the problem that the grid-connected power fluctuation of the photovoltaic power system affects the stability of grid operation, a multivariable fuzzy coordinated control strategy for photovoltaic grid-connected power fluctuation based on super-capacitor and battery is proposed. First, a multivariable fuzzy controller is established based on the grid-connected estimated fluctuation power of the photovoltaic power system and the current energy state of charge of super-capacitor and battery. The fuzzy relational matrix is used to introduce interaction effects of inputs into the fuzzy control, the fuzzy relation matrix is established by multiplying with weights, and the time constant of the low-pass filter is adjusted to coordinate the distribution of fluctuating power between different energy storage in real-time. Second, according to the SOC variation of HESS, a super-capacitor fuzzy controller and battery fuzzy controller are established to modify the charging and discharging instructions of battery and super-capacitor. The charging and discharging power of the energy storage are constraints to optimize the charging and discharging power of the energy storage, and the energy state of the HESS is updated in real-time. Finally, an overall example analysis of fuzzy coordinated control is performed to verify the effectiveness of the proposed control strategy.

“…En la búsqueda de soluciones para mejorar la eficiencia y resiliencia de las redes eléctricas ha surgido el concepto de micro-red (Alam et al, 2012).Éstos sistemas están formados por grupo de recursos interconectados de generación y consu-mo de energía, que algunas veces integran fuentes no convencionales (solar y/o eólica) y unidades de almacenamiento (baterías y vehículos eléctricos), ver por ejemplo (Bordons et al, 2015). Estas soluciones presentan alta variabilidad en la generación, debido a las fluctuaciones que presentan las fuentes renovables.…”

<p>En este artículo se propone un modelo para la predicción de demanda de energía eléctrica a corto plazo empleando técnicas de estimación Set Membership. El modelo está compuesto por una componente periódica y una componente no-lineal auto-regresiva generada por un modelo no-paramétrico adaptable que incorpora datos recientes al conjunto de identificación en cada iteración del algoritmo. El modelo es evaluado en un caso de estudio con mas de 13,000 muestras de demanda horaria a lo largo de tres años, registradas en un municipio rural de Colombia. El desempeño del estimador se compara con un modelo lineal auto-regresivo y un modelo Set Membership con conjunto de identificación fijo. Los resultados muestran que el estimador propuesto logra predecir la demanda de energía con un error RMS inferior al 2.5 % en datos de validación, empleando solo un 5 % de los datos disponibles para la construcción del modelo.</p>
