Primary and secondary frequency regulation with photovoltaic generators

2015 16th International Scientific Conference on Electric Power Engineering (EPE), 2015
With the increasing number of distributed generators which transform renewable power sources to electricity, PV generators trough invertors, when is usually difficult to make power output regulation from the primary source side, is the problem of the output power adapting according to the consumption requirements increasingly important.

Cyber Network Design for Secondary Frequency Regulation: A Spectral Approach

2018 Power Systems Computation Conference (PSCC), 2018
We present a preliminary theoretical framework based on spectral graph theory that captures how the cyber topology of a distributed secondary frequency control scheme impacts the stability, optimality, and transient performance of our power system as a cyber-physical network.

An inductive-link with a regulated secondary voltage based on frequency adjustment

2012 Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2012
This paper shows a wireless powering system for implantable biomedical devices that does not need a voltage regulator inside the body. The regulated voltage is obtained in the secondary of an inductive link and is controlled by varying the operating frequency of the inductive link.

Coordinated Vehicle-to-Grid Control to Participate in Secondary Frequency Regulation

2019 IEEE Transportation Electrification Conference and Expo, Asia-Pacific (ITEC Asia-Pacific), 2019
Since a plug-in electric vehicles (PEVs) fleet can behave like a storage system and earn extra money by participating in secondary frequency regulation (SFR), a proper method that coordinates all the PEVs within this fleet is required. This paper introduces a coordinated vehicle-to-grid (V2G) control method to enable a PEV aggregator to participate in ...

The cost of curtailing wind turbines for secondary frequency regulation capacity

Energy Systems, 2013
We analyze the cost of curtailing the active power output of a wind farm to provide secondary frequency regulation capacity. We calculate the regulation capacity available and its cost by simulating the active power output of a curtailed 100-MW wind farm with a hybrid of real wind speed data and simulated high-frequency turbulence.

Frequency Regulation by Distributed Secondary Loads on Islanded Wind-Powered Microgrids

IEEE Transactions on Sustainable Energy, 2016
Frequency regulation is critical to the successful operation of remote wind–diesel electrical grids. When the grid is in ‘wind–diesel’ mode, frequency regulation is (classically) the sole duty of the diesel electric generator (DEG). An alternative approach is proposed whereby responsibility for frequency regulation is shared by the DEG and a network of
