The content of this paper addresses possible approaches that will eventually allow the development of microgrids for small and medium size industries on a massive scale. Therefore, it addresses in a comprehensive way, the most suitable communication technologies for microgrids in this type of enterprises. Several energy sources that can be implemented in industrial microgrids are also briefly addressed, including generation and storage units frequently adopted for power supply in small scale distribution grids. The overview of communication technologies and energy sources takes into account the financial limitations of small enterprises with the purpose of assisting the study of industrial microgrid architectures. In addition, a case study is presented in order to observe how a centralized and a decentralized deployment of energy sources affect the performance of a small or medium scale industrial microgrid. Since this sector is very important for the development of modern societies, it should make use of the most advanced infrastructures in order to be more sustainable, both environmentally and competitively. The practical limitations applied to industrial microgrids (e.g., lack of standards in the grid codes, some unfit technolo gical performance and amiss system design) shows that the subject presented in this paper deserves much more research and developments. Thus, this work demonstrates the importance of the development of the microgrid for the small and medium-sized enterprises sector.

“…It is based on reducing the amplitude and frequency of the reference voltages according to the reactive Q and active P powers delivered by the inverter [17,26,27] (26) The droop control method makes possible to operate several inverters simultaneously as voltage sources [5,8]. It is based on reducing the amplitude V re f and frequency ω re f of the reference voltages according to the reactive Q and active P powers delivered by the inverter [17,26,27] …”

“…The principle of operation of the droop method can be appreciated with the help of Equations (26) and (27). On the one hand, the frequency is a global variable in a power system and in steady-state all the elements in this system operate at the same frequency.…”

“…On the one hand, the frequency is a global variable in a power system and in steady-state all the elements in this system operate at the same frequency. Thus, from Equation (27), the following relation can be written for the inverters i and j [39] (30) revealing the capacity of active power sharing of the inverters. In other words, the active power delivered by each inverter is proportional to the active power of the other inverters.…”

“…These blocks are based on a specific re-formulation of the droop method valid for grid-connected conditions. The main differences with the implementation shown in Equations (26) and (27) for islanded mode are: (1) PI controllers instead of only P controllers are used to ensure that active and reactive powers follow their references accurately; and (2) phase angles instead of angular frequencies are used due to the microgrid frequency is fixed by the utility grid frequency ω g . From [30], the voltage amplitude and phase angle of the positive and negative sequence voltages are written as…”

Several control schemes specifically designed to operate inverter-based industrial microgrids during voltage sags have been recently proposed. This paper first classifies these control schemes in three categories and then performs a comparative analysis of them. Representative control schemes of each category are selected, described and used to identify the main features and performance of the considered category. The comparison is based on the evaluation of several indexes, which measure the power quality of the installation and utility grid during voltage sags, including voltage regulation, reactive current injection and transient response. The paper includes selected simulation results from a 500 kVA industrial microgrid to validate the expected features of the considered control schemes. Finally, in view of the obtained results, the paper proposes an alternative solution to cope with voltage sags, which includes the use of a static compensator in parallel with the microgrid. The novelty of this proposal is the suitable selection of the control schemes for both the microgrid and the static compensator. The superior performance of the proposal is confirmed by the analysis of the quality indexes. Its practical limitations are also revealed, showing that the topic studied in this paper is still open for further research.
