Optimization of constant power control of wind turbines to provide power reserves [PDF]

, 2013
In several countries, the wind power penetration increased tremendously in the last years. As the current wind turbines do not participate in frequency control nor reserve provision, this may compromise the proper functioning of the primary control and ...

Stability and Frequency Regulation of Inverters with Capacitive Inertia [PDF]

, 2017
In this paper, we address the problem of stability and frequency regulation of a recently proposed inverter. In this type of inverter, the DC-side capacitor emulates the inertia of a synchronous generator.

Chance-Constrained Real-Time Dispatch with Renewable Uncertainty Based on Dynamic Load Flow

Energies, 2017
In this paper, a comprehensive real-time dispatch model considering renewable uncertainty based on dynamic load flow (DLF) is proposed. Through DLF, the primary and secondary frequency regulation amount caused by the variation of renewable energy as well

A Solid State Transformer model for power flow calculations [PDF]

, 2017
This paper presents the implementation of a Solid State Transformer (SST) model in OpenDSS. The goal is to develop a SST model that could be useful for assessing the impact that the replacement of the conventional iron-and-copper transformer with the SST
