Electric vehicles are able to provide immediate power through the vehicle-to-grid function, and they can adjust their charging level when in grid-to-vehicle mode. This allows them ancillary services such as frequency control. Their batteries differ from conventional energy storage systems that owner’s requirement constraint must be met participate a control system. An optimization problem was d...

This paper presents one of the first real-life demonstrations coordinated and distributed resource control for secondary frequency response in a power distribution grid. A series tests involved up to 69 heterogeneous active energy resources consisting air handling units, unidirectional bidirectional electric vehicle charging stations, battery storage system, 107 passive building loads solar pho...

To fully utilize the frequency regulation (FR) capability of wind turbines (WTs) and to avoid a secondary drop caused by rotor speed recovery, this paper firstly proposes an FR evaluation method for farms based on principle equal rotational kinetic energy WTs, analyses essence cooperative recovery WTs. Based these, synthetic inertia control (CSIC) considering is proposed. By introducing coeffic...

Frequent and inadequate power regulation could significantly impact the main shaft mechanical load fatigue of wind turbines, which imposes a stringent requirement to perform frequency regulation. However, existing work on mainly uses torque compensation improve response, while few them consider caused by controller. In this paper, can be mitigated in all speed sections thanks proposed controlle...
