Because of small capacity and low inertia of the inverter based micro-source, loads changing have great impact on the frequency and voltage of islanded micro-grid. A novel frequency control strategy of micro-source based on the secondary frequency regulation of power system is proposed in this paper. Traditional droop control strategy of micro-grid can'

Unit Commitment with Integrated Energy System Considering Primary and Secondary Frequency Regulation
2021 5th International Conference on Green Energy and Applications (ICGEA), 2021With the development of renewable energy generation (REG) such as wind power, the economic operation of power system is greatly challenged by the phenomenon of wind curtailment. To reduce the operation cost of power system and improve the accommodation capacity of renewable energy, a unit commitment (UC) model with integrated energy system (IES ...

Frequency Regulation by Distributed Secondary Loads on Islanded Wind-Powered Microgrids
IEEE Transactions on Sustainable Energy, 2016Frequency 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

Currently, Non-Programmable Renewable Energy Source (NPRES) generation contributes significantly to demand supply, but participation to ancillary services is still limited to emergency support (e. g. curtailment of energy production in case of over-generation, fast active power reduction in case of large over-frequency transients).

2000 Power Engineering Society Summer Meeting (Cat. No.00CH37134), 2002
This paper presents the method developed and applied to evaluate the costs for primary and secondary regulation of frequency in the economic transactions between the companies forming the Argentinian electric system. To consider the primary frequency regulation, the method is based on a redistribution of the income that the generators collect for ...

Design of Fuzzy Regulator for Power System Secondary Load Frequency Control
2002The stability analysis of nonlinear system that is harmonically linearised is given[10, 3, 11]. With the introduction of fuzzy regulator the nonlinear system consists of linear part and two nonlinear parts. The stability analysis is conducted by use of describing function method and Hurwitz stability criterion.
