This paper analyzes the provision of a new dynamic frequency support to isolated power systems using a fast control of the load through the grid voltage. This control has appealing advantages, among which: 1) no impact on customers provided that their voltage remains within admissible limits, 2) the only communication that is required is the grid voltage itself and 3) the response is almost instantaneous...
Possible interconnection of the European Network of Transmission System Operator for Electricity (ENTSO-E) and joint power system of the former USSR (IPS/UPS) will cause the necessity to evaluate the security state of large transmission systems. One important problem for a large interconnection is the frequency control. This paper considers distinctions of frequency control in interconnected power...
In the last two decades, there has been an increasing investment on renewable technologies. To this extent, massive number of small wind turbines and Photovoltaic Arrays are being installed and integrated in electrical power systems. This leads to a trend to convert current centralized power production by rotating machines to decentralized power electronic interfaced production. A potential impact...
A high penetration of renewable energy sources challenges future grid frequency control. Decentralized demand control can contribute to this frequency control. In this paper a method is proposed where residential demand is controlled to support the frequency. The total customer welfare remains maximal during this support by applying utility functions for each device. A large scale isolated power system...
The purpose of this paper is to investigate the frequency support in low inertia systems that could be provided by a wind farm during load mismatch. Temporary instant inertia support and inertia emulation support are evaluated and compared. An improved control strategy is presented giving quick power delivery even during low wind speeds. The proposed model can support a loss of generation of 0.1 pu...
In perspective, by 2030, a change of the fuel/ technology structure of capacity power will take place during the next dozen or so years in many countries of the European Union. Such changes are also planned in the Polish Power System (NPS) structure of capacity power which, in addition to the economic and environmental is also reflected under the angle of frequency control and tie-line power in interconnected...
The expected rollout of plug-in Electric Vehicles (EV) in the next few years will generate additional constraints to the electrical power systems if badly managed: demand increase and risk of peak loads. Nevertheless, these EV could also be an opportunity thanks to their storage batteries. Vehicles could then be harnessed to provide services such as peak reduction or frequency regulation. Previous...
