Original scientific paperSolar power is the major renewable energy source opted by developing countries as stand-alone / Grid enabled system. Industries and educational institutions are opting for solar energy to combat power crisis. This paper proposes knowledge based, self configurable, smart controller to efficiently use solar energy according to load, under frequent grid failure environment. It is enabled with fault identification and isolation. Extension to higher power capacity is easily achieved with plug and play mechanism. Proposed control architecture is implemented using Field Programmable Gate Array (FPGA), that supports modular level implementation with well defined interfaces for each sub-system. It can be used with low power as well as high power photo-voltaic system. Efficiency of the proposed architecture is demonstrated for the photo-voltaic system installed in educational institution.Key words: Field Programmable Gate Array, Photo-voltaic system, Pulse width modulation, Stand alone system. Sustav za efikasno upravljanje solarnom energijom. Solarna energija spada među glavne obnovljive izvore energije odabrana od strane zemalja u razvoju kao samostalnih izvora ili umrežene s ostalim izvorima. Industrija i edukacijske institucije predlažu solarnu energiju u borbi protiv energetske krize. U ovome radu predstavljen je samokonfigurabilan regulator za efikasno korištenje solarne energije s obzirom na opterećenje ičeste promjene u mreži. To je omogućeno uz identifikaciju kvara. Ekstenzija na visoke snage jednostavno se postiže sa uređajem koji se može odmah koristiti. Regulator je implementiran koristeći programirljive logičke sklopove (FPGA) koji podržavaju modularnu implementaciju svake razine sa sučeljem prema svakom podsustavu. Predloženi sustav može biti korišten za niske snage kao i za visoke snage kod fotonaponskih sustava. Efikasnost predložene arhitekture testirana je na fotonaponskom sustavu postavljenom na edukacijskoj instituciji.Ključne riječi: programirljivi logički sklopovi, fotonaponski sustav, pulsno-širinska modulacija, samostalni sustav

Original scientific paperIn this paper the state of the art of distributed maximum power point techniques for photovoltaic systems is discussed. Modern applications of photovoltaic systems in urban context and to sustainable mobility require the proper facing of drawbacks due to partial shading and different orientations of the cells the photovoltaic source is made of. The latest architectures proposed in literature are reviewed and their points of strength and weakness are discussed. Finally, the products that are currently available on the market are presented and their fields of application and features are overviewed.Key words: Maximum power point tracking, Photovoltaic systems Distribuirano slijedenje točke maksimalne snage: izazovi i komercijalna rješenja. U ovomčlanku opisane su suvremene napredne tehnike za distribuirano postizanje maksimalne snage fotonaponskih sustava. Moderne aplikacije fotonaponskih sustava u urbanom smislu i održivoj mobilnosti zahtijevaju pravilno suočavanje s nedostacima uslijed djelomičnog zasjenjenja i različitih orijentacijaćelija fotonaponskog izvora. Razmatraju se najnovije arhitekture predložene u literaturi te su objašnjene njihove prednosti i nedostaci. Naposljetku, izloženi su trenutno dostupni proizvodi na tržištu te je dan pregled njihovih karakteristika i područja primjene.Ključne riječi: slijedenje točke najveće snage, fotonaponski sustavi

“…The power subsystem ( Figure 1) has basically three components (the step-up DC/DC converter, the DC bus, the DC/AC inverter and a LCL filter) for power conditioning, two sets of contactors (DC and AC) to operate the hardware platform, the EMI filter and the isolation transformer (Yd5, Rt=0.247Ω, Xt=0,201Ω) The DC/DC converter is used to increase the DC bus voltage required for reducing the number of PV panels with a series connection [4,5]. We have chosen a rated power of 20 kW, following the trends that the Spanish government indicates to obtain a better feed-in tariff with a roofmounted system [6].…”

This paper presents a dual digital signal processor (DSP) hardware architecture for a grid-connected photovoltaic interface test benchmark, based on a cascade DC/DC converter and DC/AC inverter, with coordinated control algorithms. The control hardware has been designed to test distributed generation (DG) interfaces to be integrated in a hierarchical structure of computational agents, to apply distributed control techniques to the power system management. The proposed dual DSP architecture enables the programming of the control software for the DC/DC converter and the DC/AC inverter in the same processor, to keep the other one for additional operations that are required when there is a high degree of interaction between the DG 2 unit and the rest of the electrical grid components. The hardware architecture has been tested in several real situations such as power factor correction and anti-islanding protection.
