The micro grid is an integrated form of distributed energy resources. The interconnection of small modular generation technologies at the medium voltage (MV) and low voltage (LV) distribution levels may affect the power system performance. This type of the networks will use the best combination of control and modeling technologies to meet the specific capacity, quality and reliability. For the MG...
Inverters are a universal interface to inject the power produced by distributed power generation in stand-alone loads, micro-grid or the main electrical grid. The control system of a universal inverter should be designed in order to manage the different connections. This paper is an attempt to provide an overview with attention paid to current/voltage control of the converter and direct/inverse droop...
This paper proposes a new method to determine the droop of the inverter-based distribution generations (DGs). Conventionally, inverter-based DGs have droop controller with fixed slope according to their capacity. Some additional control methods have been proposed in order to enforce the maximum or minimum limit of a unit. However, in some severe cases, the frequency deviation during the islanded mode...
