This paper presents a summary of the most important characteristics of wind turbine generators applied in modern wind power plants. Various wind turbine generator designs, based on classification by machine type and speed control capabilities, are discussed along with their operational characteristics, voltage, reactive power, or power factor control capabilities, voltage ride-through characteristics,...
This technical paper provides the basic guidelines for the application of reactive compensation systems to be used as part of a wind power plant. A brief history of wind plant reactive compensation system is discussed, then the fundamental needs of why reactive compensation is required. The paper will then provide some alternatives for reactive compensation, how to size the reactive compensation,...
The value of intermittent wind generation is significantly affected by their penetration and concentration, and is further affected by their location within a network. This is because the location and penetration level of wind generation will result in significant impact on power flow distribution across the network. When increasing the penetration and concentration of wind generation in a power system,...
Distributed energy resources (DE) with power electronics (PE) interfaces with the right control are capable of providing reactive power related ancillary services; voltage regulation in particular has drawn much attention. In this paper the problem of how to coordinate control multiple DEs to regulate the local voltage in the distribution system is addressed. A control method for voltage regulation...
In this paper, the amount of dispatchable responsive demand from domestic sector with different methods of charging has been evaluated and the benefits of responsive demand in order to increase the security, reducing the emissions and production cost in an intermittent system has been presented. Additional benefit; the value of wind is also demonstrated. The quantification was performed on the IEEE...
Embedded generators are expected to play an increasingly important role in future energy supply. They could potentially benefit networks from loss reduction and deferred or delayed investment. Equally, they can increase network investment through inappropriate siting, potentially leading to expensive network upgrading and expansion. This cost/benefit of embedded generator is not reflected by any of...
This paper describes the principle and implementation of a new MW+MVAr-miles based charging methodology for pricing distribution networks. The charging methodology was developed with an aim of reflecting the true cost and benefit of network users, especially embedded generators (EGs). The proposed charging methodology respects the cost to a network due to both real and reactive power, i.e. power factor...
This paper describes the principle and implementation of a new MM+MVAr-Miles based charging methodology to allocate the existing distribution network's annuity cost. The proposed charging methodology separates network facilities' cost due to the respective real and reactive power flows. The costs are then allocated to network users according to their nature (demand or generation) and their power factors...
