Abstract. The concept of microgrid was first introduced in 2001 as a solution for reliable integration of distributed generation and for harnessing their multiple advantages. Specific control and energy management systems must be designed for the microgrid operation in order to ensure reliable, secure and economical operation; either in grid-connected or stand-alone operating mode. The problem of energy management in microgrids consists of finding the optimal or near optimal unit commitment and dispatch of the available sources and energy storage systems so that certain selected criteria are achieved. In most cases, energy management problem do not satisfy the Bellman's principle of optimality because of the energy storage systems. Consequently, in this paper, an original fast heuristic algorithm for the energy management on stand-alone microgrids, which avoids wastage of the existing renewable potential at each time interval, is presented. A typical test microgrid has been analysed in order to demonstrate the accuracy and the promptness of the proposed algorithm. The obtained cost of energy is low (the quality of the solution is high), the primary adjustment reserve is correspondingly assured by the energy storage system and the execution runtime is very short (a fast algorithm). Furthermore, the proposed algorithm can be used for real-time energy management systems.

“…Integrating the micro grid system and smart grid is an effective approach to make the best of distributed generation [3]. However, the distributed renewable energy power generation from renewable energy sources have exhibited intermitent and random characteristics that restrict its power generation capability and its operating stability [4,5]. The micro grid can join the distributed generation and energy storage equipment together through an advanced control system, and form a controllable cell.…”

Original scientifica paper Recently, there has been an increasing interest in using distributed generators (DG) not only to inject power into the grid, but also to enhance the power quality. In this study, a space voltage pulse width modulation (SVPWM) control method is proposed for a synchronous grid-connected controller in a wind-solar-storage micro grid. This method is based on the appropriate topology of the synchronous controller. The wind-solar-storage micro grid is controlled to reconnect to the grid synchronously while maintance or repair is being completed to the power source equation DG at some point, the voltage difference that exists between DG and both sides of the node, a large and sudden electrical surge when DG is reconnected to the grid. It also affects the normal work of the other DG and power quality of a necessary load, and could even seriously paralyze the whole system. So, the topological structure and control method of the synchronous grid-connected controller are discussed in detail and simulation results are presented. The results demonstrate the effectiveness of the proposed method in the synchronous grid-connected controller for the wind-solar-storage micro grid. Keywords: distributed generator (DG); micro grid; SVPWM; synchronous grid-connected controllerPrimjena sinkronog mrežno povezanog upravljačkog uređaja u mikro mrežu pohrane energije vjetra-sunca Izvorni znanstveni članak U zadnje je vrijeme poraslo zanimanje za uporabu raspodjelnih generatora (DG) ne samo za uključivanje energije u mrežu već i za poboljšanje kvalitete energije. U ovom se radu predlaže metoda regulacije SVPWM (space voltage pulse width modulation) za sinkroni mrežno povezani upravljački uređaj u mikro mrežu pohrane energije vjetra-sunca. Ta se metoda zasniva na odgovarajućoj topologiji sinkronog upravljačkog uređaja. Mikro mreža pohrane energije vjetra-sunca upravlja se tako da se istovremeno uključi u mrežu dok se ne završi održavanje ili popravi ujednačeni izvor energije DG u nekoj točki, razlika u naponu koja postoji između DG i obje strane čvora, naglo povećanje električne energije kada se DG ponovo uključuje u mrežu. To također utječe na normalan rad drugog DG i na kvalitetu potrebnog opterećenja, a moglo bi čak i ozbiljno paralizirati čitavi sustav. Stoga se topološka struktura i kontrolne metode sinkronog upravljačkog uređaja detaljno analiziraju i prezentiraju se rezultati simulacije. Prezentirani rezultati pokazuju učinkovitost predložene metode sinkronog upravljačkog uređaja povezanog s rešetkom u mikro mrežu pohrane energije vjetra-sunca.Ključne riječi: raspodjelni generator (DG); mikro mreža; sinkroni mrežno povezani upravljački uređaj; SVPWM

Abstract.One of the best solutions to face the problems in the current European electric systems is based on the implementation of microgrids as a way of increasing the consumption from renewable energy (RE) sources, improving energy efficiency, decreasing GHG emissions and, as a consequence, complying with European Commission (EC) 2020 targets. In this line, different EU regulations have been established but the particularities of each member state regulatory framework could appear as a barrier. For this reason, it is important to study how member states are carrying out the tasks associated with the penetration of microgrids, studying how European directives are transposed and incentives introduced. Besides, representative projects and demonstration cases for microgrids are shown, in order to determine the feasibility of the introduction of this novel concept in real situations.
