A Virtual Inertia Method for Stability Control of DC Distribution Systems with Parallel Converters
نویسندگان
چکیده
DC distribution systems are a typical power electronic system with low inertia, low-rotational kinetic energy, and poor antidisturbance capability when loads fluctuate or parameters change. In this paper, virtual inertia control an additional first-order filtering link is proposed on the basis of P-Udc droop control. The results simulations experiments verify that reduces voltage change rate improves by adjusting capacitance value side converter, which can achieve smoother more accurate suppress continuous oscillation.

A New Intelligent Controller for Parallel DC/DC Converters
In this paper, the immune controller, is used to control the paralleled DC-DC converters. A PID controller is first applied and its coefficient is optimized using an intelligent (PSO) algorithm. Immune controller is then added to PID controller and an immune PID controller is formed. Two methods have been suggested to determine non-linear behavior of immune controller. In the first method, an e...

متن کاملEnergy-Efficient Electrical Power Distribution with Multi-Agent Control at Parallel DC/DC Converters
Consumer electronics are pervasive. It is impossible to imagine a household or office without DVD players, digital cameras, printers, mobile phones, shavers, electrical toothbrushes, etc. All these devices operate at different voltage levels ranging from 1.8 to 20 VDC, in the absence of universal standards. The voltages available are however usually 120/230 VAC at 50/60 Hz. This situation makes...

متن کاملDesigning a new robust control for virtual inertia control in the microgrid with regard to virtual damping
Background and Objectives: Virtual inertia control, as a component of a virtual synchronous generator, is used for the implementation of synchronous generator behaviour in microgrids. In microgrids that include high-capacity distributed generation resources, in addition to virtual inertia, virtual damping can also lead to improvement of frequency stability of the microgrid. The purpose of the c...
