Microgrids are, as their name implies, real-time networks operating between producers, distributors and consumers. Aim of this work is to model and simulate operation of microgrids, including micro power plants, photovoltaic panels, wind farms, diesel power and storage energy, and finally we will apply the model in real time simulation thanks to MEGASIM of the RT-LAB platform Application of this work will be in southern Algeria area, where climate is hot, sunny and arid, and daytime temperatures are very high. It means that both of wind and photovoltaic energies are widely suitable in this location. Results obtained by this tool will allow us to have a very accurate vision of Micro grid operation, in term of power flow or fault responses.

In recent years, deregulation, open access, and co-generation in electrical power system are creating transmission voltage sags, swells, forced outages, and frequently followed by black-outs, congestion scenario, and many such problems. Reactive power limit is one of the major causes of voltage instability in the power system, and improving the system's reactive power handling capacity via Flexible AC transmission System (FACTS) devices is one of the remedies for prevention of voltage instability. The typical representatives of parallel FACTS devices for its avoidance are Static Synchronous Compensator (STATCOM) and Static VAR Compensator (SVC). Real-Time Simulator facilitates a physically large and spatially diverse or distributed power system to be accurately simulated in laboratory, and physical devices, like controllers or protection equipment can be tested in real time, even with introduction of faults, overloads, loss of generation condition, and with many more conditions for stability analysis purpose. This paper presents comparison of power flow parameter and the performance characteristic of the controllers on Real-Time Simulator OPAL-RT-OP4510 with SVC, and STATCOM. The waveforms of voltage, current, active and reactive power during the Real-Time execution are taken from the simulation environment to the outside world, using input/output devices, and seen on Digital Storage Oscilloscope (DSO). The validation is done on multi-machine-9-bus system. The results of Real-Time Simulation during LLLG fault indicate that STATCOM supplies reactive power independent of line voltage, whereas SVC behaves as constant susceptance when the reactive power required by the system is above its rated capacity. The power flow parameters with both the controllers are comparable during steady state operation.

This paper describes a control methodology for electronic power converters distributed in low-voltage microgrids and its implementation criteria in general microgrid structures. In addition, a real-time simulation setup is devised, implemented, and discussed to validate the control operation in a benchmark network. Considering these key aspects, it is shown that operational constraints regarding the power delivered by sources, flowing through network branches, and exchanged at the point of connection with the main grid can generally be fulfilled by the presented control approach. The control is performed considering a cost function aiming at optimizing various operation indexes, including distribution losses, current stresses on feeders, voltage deviations. The control system allows an enhanced operation of the microgrid, specifically, it allows dynamic and accurate power flow control enabling the provision of ancillary services to the upstream grid, like the demand–response, by exploiting the available infrastructure and the energy resources. Then, the validation of the approach is reported by using a real-time simulation setup with accurate models of the power electronic converters and related local controllers, of the grid infrastructure, of the power flow controller, and of the communication network used for data exchange. It is also shown that the implemented platform allows to fully reproduce, analyze, and finally validate all the relevant steady-state and dynamic behaviors related in the considered scenario.
