CONTEXT

5. 5
◎ GRID-FORMING CONVERTERS ARE POWER ELECTRONIC DEVICES THAT
CAN GENERATE ELECTRICITY AND INJECT IT INTO AN ELECTRICAL GRID.
5
INTRODUCTION

6. 6
◎ GRID-FORMING CONVERTERS TYPICALLY WORK BY
CONVERTING THE DIRECT CURRENT (DC) OUTPUT OF A
RENEWABLE ENERGY SOURCE, SUCH AS SOLAR PANELS OR A
WIND TURBINE, INTO ALTERNATING CURRENT (AC) THAT CAN
BE FED INTO THE GRID.

COMPONENTS

8. 8
◎ THERE ARE SEVERAL APPROACHES THAT CAN BE USED TO
CONTROL A GRID-FORMING CONVERTER:
I. PROPORTIONAL-INTEGRAL-DERIVATIVE (PID) CONTROL
II. MODEL PREDICTIVE CONTROL (MPC)
III. DROOP CONTROL
IV. VIRTUAL OSCILLATOR CONTROL (VOC
V. HYBRID CONTROL
