“…Modul CCGX ima nekoliko portova za povezivanje sa ruterima. Kontrolno kolo svakog od invertora je realizovano sa dve povratne sprege, jedna po izlaznom naponu i druga po izlaznoj struji [17][18][19][20][21]. Signali povratne sprege po izlaznom naponu (označen sa Vout) i po izlaznoj struji (označen sa Iout ) se dovode na analogne ulaze kontrolnog kola.…”

“…Principska blok šema kontrole i komunikacija u sklopu hibridnog napajanja potrošača u sistemu zalivanja na parceli u mestu Belegiš U trofaznoj sprezi invertora koja je prikazana na Slici 5 se ostvaruje sinhronizacija invertora na takav način da su fazni pomeraji referentnih signala za upravljačka kola invertora SLAVE1 i SLAVE2 jednaka θ+120° i θ-120° respektivno, gde je θ fazni pomeraj MASTER upravljačkog kola. Uobičajeno je da se usvaja da je fazni pomeraj MASTER invertora θ=0°[20,21]. Ovaj invertor je putem VEbus komunikacionog porta povezan sa lokalnim kontrolerom CCGX.…”

The paper presents the implementation of remote monitoring and control of a hybrid power plant for irrigation of crops on a private agricultural plot of about 10ha in the town of Belegiš. The hybrid irrigation system is based on the dominant use of renewable energy sources (RES), solar and wind, with the use of a strong 48V/1000Ah battery bank and a 7.5 kW dieselelectric generator as a back-up power source. The used irrigation pump is driven by a three-phase asynchronous electric motor with a power of 5.5 kW, which is supplied by a frequency regulator. Frequency regulation is used to pressure and flow control in the irrigation pipeline and provides additional efficiency of the system. As part of the system, all necessary elements of power electronics (solar and wind MPPT chargers, inverters and frequency regulator) have been implemented, which are networked together. The entire control system is based on a control module that controls the charging of the battery bank, controls the operation of the inverter, and acquires all the necessary measurements in the hybrid power supply system. Through the ETERNET port, this module is connected to the central computer that controls the operation of the entire hybrid plant. This computer is based on BEAGLEBONE BLACK processor. This module has the ability to receive and send data remotely via GSM/GPRS, a module through which it is possible to monitor all relevant parameters of the system, and it is also possible to remotely control of the irrigation system.

“…2008). Therefore, efforts to improve energy efficiency are conducted by using maximum power point tracking (MPPT) control [1], so that the maximum power extracted from the PV array in real time becomes indispensable in solar power systems. There are many techniques to get the MPP such as the P&O (Perturb &Observation), IC (Incremental Conductance) & FLC (Fuzzy Logic Control).…”

This paper presented the Deep detail of ANFIS and Grid Connected. Photovoltaic power generation system required an effective controller to overcome sudden irradiance change and to maximize their efficiency in order to be more efficient & more precise. This paper proposed an approach of MPPT based on a voltage control approach of power converter with the use of the Adaptive Fuzzy logic controller (Adaptive FLC). The input voltage reference is adaptively perturbed with variable steps until the maximum power is reached. A statespace model is derived through averaging method, with the control input being the modulation depth of the proposed Inverter. The proposed control scheme achieved stable condition in the control region of the PV panel and eliminated the steady state oscillations when there is sudden change of irradiance in the maximum power operating point. Furthermore, the PV system became more efficient, as proven by sudden change in radiation conditions for 0.2 seconds, where energy can be saved approximately 95%. As the max error percentage (Kindly refer to Fig. 29)
