This paper investigates the potential impact of a fleet of electric vehicles charging on the cost of electricity generation, greenhouse gas emissions (GHG) and power system demand through low voltage residential demand-side management (DSM). The proposed optimisation algorithm is used to shift electric vehicles charging loads to minimize the combined impact of three key parameters: financial, environmental,...
This paper explores smoothing in the net real power generated by arrays of point absorber type wave energy converters (WECs) brought about by spacing WECs appropriately within the array. Smoothing is measured by assessing the voltage flicker introduced by injecting the generated power into electricity networks. Uniformly spacing WECs at 0.25λpeak, where λpeak is the wavelength corresponding to the...
This paper presents a simulation tool for the design and analysis of offshore ocean energy array networks. The tool integrates a number of modules which are divided into two core functions: the automation of the cable laying algorithm and subsequent creation of the network model, and the other performing the power flow analysis. The results of the power flow analysis are used to inform the user of...
This paper presents a component-based modelling approach for developing time-varying harmonic current injection models of the residential load sector. Some initial results of the model are also presented to demonstrate the temporal variations in low-voltage (LV) residential harmonics. The level of detail afforded by the model is illustrated using the proliferation of compact fluorescent lamps as a...
The paper presents a detailed study of the potential impact on the cost and greenhouse gas emissions (GHG) through low voltage (LV) residential demand-side management (DSM). The proposed optimisation algorithm is used to shift non-critical residential loads, with the wet load category used as a case study, in order to minimise the total daily cost and emissions of GHG due to generation. This study...
This paper describes a wave-to-wire model of an array of wave energy converters developed in MATLAB/Simulink. The effects of connecting a 1 MW wave farm to a weak, rural electricity network are investigated. Impacts of the wave farm on voltage quality are examined and both conventional and more intelligent control methods by which these impacts can be mitigated are discussed. The control methods compared...
This paper describes a wave-to-wire model of an array of wave energy converters (WECs) developed in MATLAB/Simulink. The model has been used to study the effects of connecting a 1MW wave farm to a weak, rural electricity network. Voltage quality issues are examined and methods by which these impacts can be mitigated are discussed. The operation of the wave farm using four different controllers used...
