This paper presents a new robust nonlinear excitation controller design for synchronous generators in multimachine power systems to enhance the transient stability. The mismatches between the original power system model and formulated mathematical model are considered as uncertainties, which are modeled through the satisfaction of matching conditions. The exogenous noises appearing from measurements...
This paper presents a hierarchical transactive energy management framework for a residential microgrid to share excess energy of prosumers with neighbors. A three-level hierarchical structure is proposed in this paper which facilitates energy management in different houses, energy sharing and transactions among neighbors and with the grid. The priority of sharing energy among different houses in a...
Integration of large-scale renewable energy (RE) sources in particular, wind and solar energy into the grid introduces current and voltage harmonics due to power electronics devices as well as inverter connected into the RE sources. Ensuring adequate harmonics in the line currents of RE integrated power system is one of the biggest challenges today. Therefore, this study investigates the potential...
Offshore wind turbine requires more systematized operation and maintenance strategies to ensure systems are harmless, profitable and cost-effective. Condition monitoring and fault diagnostic systems ominously plays an important role in offshore wind turbine in order to cut down maintenance and operational costs. Condition monitoring techniques which describing complex faults and failure mode types...
In this paper, a distributed multi-agent scheme is presented for reactive power management with renewable energy sources (RESs). The multi-agent system (MAS) framework is developed for distribution systems to improve the stability which is mostly dominated by voltage and the agents in this framework coordinate among themselves using online information and energy flow. In this paper, the agents basically...
Increasing household energy consumption and increasing primary energy cost urged to improve home energy efficiency. Improved energy management can suggest the ways to improve home energy efficiency. Various home appliances are the prime cause to the increased power demand. Appliance's energy rating information helps to develop awareness and reduce energy consumption. Load shifting can help to reduce...
This paper investigates the impacts of distributed generator such as solar PV and energy storage on the utility grid. Initially experiment was conducted by increasing PV penetration into the grid and analysed the voltage fluctuation at PCC and harmonic emission on the network. Later, a software model was developed and same impacts were investigated with increased penetration of solar PV. The model...
Penetration of solar energy is increasing rapidly in Australia over the last decade due to its availability and climate-friendly attributes. Solar energy is free from green house gas (GHG) emission and plays a key role in developing a sustainable power system for the future. However, the intermittent nature of solar energy creates a number of potential challenges in integrating large-scale photovoltaic...
Energy storage is the key building block for effective utilization of Renewable energy (RE). Among different distributed generators (DG), solar Photovoltaic (PV) is one of the most popular method in RE extraction. However PV cannot support the load at steady rate for whole day and storage helps in timely load demand and adds flexibility in load management. Moreover storage indirectly helps in reducing...
Occurrences of underground cable faults in the power transmission and distribution system is unavoidable due to several reasons. Long outage of power supply can cause the power distributors and retailers heavy loss of revenue and discomfort of the customers. Therefore, a quick detection and rectification of the faults is a major concern of the power distributors and retailers. This paper reviews a...
Computational Intelligence (CI) holds the key to the development of smart grid to overcome the challenges of planning and optimization through accurate prediction of Renewable Energy Sources (RES). This paper presents an architectural framework for the construction of hybrid intelligent predictor for solar power. This research investigates the applicability of heterogeneous regression algorithms for...
Demand management is mechanism to shift the demand of electricity from peak to off-peak to use the available energy as efficiently as possible without requiring additional generation capacity or transmission and distribution infrastructure. Demand response is a special type of demand management which motivates the customers to respond to electricity prices over time. The recently proposed demand response...
Capricorn Coast's is the most promising and growing regions in Queensland, Australia due to the national and international ecological icon Great Keppel Island and the Great Barrier Reef. Over the last couple of decades, these places attracted the attention of the local communities, national and international tourists which caused steady growth of population in the Capricorn Coast region. This growing...
Renewable energy is starting to be used as the panacea for solving climate change or global warming problems. Therefore in the starting of 21st century, Government, utilities and research communities are working together to develop a climate-friendly power generation systems for a sustainable society by increasing large-scale energy generation from renewable energy sources. However, due to the intermittent...
