Operation and stability analysis for standalone microgrid through simulations in DigSilent software

The operation of the off-grid system consisting of projectable PV panel array and two dieseis (one in reserve) generators SDMO J200K with 160 kW installed capacity are considered in this article. The aim of the study is to make a stability analysis of the system with an evaluation of problems can occur and their possible solutions, which keep the system operational. Three possible faults at generator, PV system and battery storage sides were simulated in DigSilent software. The results obtained for five different operational scenarios and show application possibilities in terms of the most critical regime.
