Attaining reactive power capability requirements for offshore wind power systems

2024 3rd International Conference on Energy Transition in the Mediterranean Area (SyNERGY MED)
The prospected diffusion of offshore wind farms (OWFs), to be connected to high-voltage transmission networks, arises the need of dealing with specific technical requirements posed in grid codes by transmission system operators (TSOs). Among them, the compliance with specific reactive power capabilities at point of common coupling can have significant ...

A grid tie micro inverter with reactive power control capability

AEIT Annual Conference 2013, 2013
The focus of this paper is a 350VA rated grid tie micro inverter for residential photovoltaic installations with reactive power control capability. The need for reactive power control of small distributed generation systems stems from the opportunity to provide localized distribution network stabilization and reduction of transmission line losses.

Attaining Grid Code Reactive Power Capabilities for Photovoltaic Power Plant

2024 AEIT International Annual Conference (AEIT)
The increasing diffusion of large-scale photovoltaic (PV) systems, to be directly connected to high-voltage transmission networks, arises the need of dealing with specific technical requirements posed in grid codes by Transmission System Operator (TSO) for a feasible connection.

Optimizing nonutility generating facility reactive power export and import capability

1999 IEEE Industrial and Commercial Power Systems Technical Conference (Cat. No.99CH36371), 2003
As new merchant power plants and nonutility generating facilities (NUGs) are added to the utility grid system, their overall generating capability becomes significant to independent system operators (ISO). These facilities deliver real power (MW) to the utility grid as-well-as having the capability to export and import reactive power (MVAr).

A cage rotor induction generator capable of supplying reactive power

2013 IEEE International Symposium on Industrial Electronics, 2013
This paper describes the operation and control of a cage induction machine generator developed to enable control of the reactive power delivered to the utility grid. The topology consists of an open winding induction machine connected to a 3-phase voltage source converter bridge using a floating dc-link capacitor.

Reactive power capability analysis of a photovoltaic generator for large scale power plants

5th IET International Conference on Renewable Power Generation (RPG) 2016, 2016
Currently, the installation of photovoltaic power plants (PVPPs) integrated with the transmission system is becoming common. This interconnection must obey the grid codes of the transmission system operator. The requirements of these grid codes are related to the response during faults, frequency, voltage support, and the regulation of active and ...

Optimal capacity of PV inverter considering reactive power capability and active power curtailment

2017 Nineteenth International Middle East Power Systems Conference (MEPCON), 2017
The penetration of photovoltaic (PV) systems has recently been increased in distribution systems. Many practical problems are resulted by the fluctuating PV systems, including voltage rise/drop and increasing the total active/reactive losses. In this paper, we propose a method for solving the practical problems associated with PV by optimally ...

ESTIMATION OF REACTIVE POWER EXPORT AND IMPORT CAPABILITY FOR NON-UTILITY GENERATORS

Proceedings of 1995 Industrial and Commercial Power Systems Conference, 1997
Non-utility generators (NUG's) are typically required by their electric power sales agreement to have the capability to supply power to the purchasing utility near unity power factor. With the advent of large combustion turbine generators, many NUG's are simple or combined cycle facilities with generating capacities in excess of 100 MW.

Reactive Power Capability of Wind Turbines Based on Doubly Fed Induction Generators

IEEE Transactions on Energy Conversion, 2011
With the increasing penetration of wind turbines (WTs) grid utilities require extended reactive power supply capability not only during voltage dips but also in steady-state operation. WTs with doubly fed induction generators (DFIG) are able to control active and reactive power independently.
