Microgrid reactive voltage stabilizer
Thus, a coordinated compensation of reactive sources has to be implemented to avoid a fast voltage collapse by proposing a Microgrid Voltage Stabilizer (MGVS). This stabilizer is desirable to improve the dynamic voltage profile and is tested at a 21-bus IEEE microgrid system. . ABSTRACT: Microgrids are used as controllable units connected to power grid, in which the electrical distances between reactive power sources and the loads that need the reactive compensation are small. Meanwhile, a voltage recovery. .Read More Download PDF
