Studying the property of combination renewable energy sources in existing power systems is great importance, and especially case deregulated systems. The uncertainty largest barrier to integrating renewable-energy-producing units into electrical infrastructure. Due its uncertainty, wind an system requires extra consideration. In this work, impacts farm (WF) integration a pumped hydroelectric st...

The design of an experimental flexible energy measurement system consisting of a DSP, sensor and communication units is treated. This system is intended to be used in modern electricity distribution networks, characterized by multiple suppliers in a deregulated market, bi-directional energy flows due to distributed generation and a diversified demand for the quality of electricity delivery. Var...

This paper deals with the optimal control problem that arise when a hydraulic system with fixed-head hydroplants is considered. In the frame of a deregulated electricity market the resulting Hamiltonian for such systems is linear in the control variable and results in an optimal singular/bang-bang control policy. To avoid difficulties associated with the computation of optimal singular/bang-ban...

Load frequency control forms an essential component of Automatic Generation Control, which helps to maintain the power system frequency constant while maintaining the tie-line power flow with neighbouring áreas at scheduled values for an interconnected power system. With deregulation, the structure of electric power industry is changed thoroughly with multiple bilateral transactions taking plac...

Since the pilots’ dispute ended in 1989, globalisation has fundamentally altered the environment in which pilots establish their terms of employment. This paper argues that pilot labour relations have been affected by globalisation in three ways. First, the Australian airline industry was deregulated in 1990. Second, the introduction of the Workplace Relations Act (1996) deregulated the Austral...

In planning studies, the conventional approach for steady state contingency analysis is to test all contingencies sequentially for evaluating system performance and reliability. This analysis consists of simulating outages of one or more generating units and transmission lines to study their effects on bus voltage, generator MVAR outputs and line power flows. But new challenges and uncertaintie...

We investigate how various institutional settings affect a network provider's incentives to invest in infrastructure quality. Under reasonable assumptions on demand, investment incentives turn out to be smaller under vertical separation than under vertical integration, though we also provide counterexamples. The introduction of downstream competition for the market can sometimes improve incenti...

This paper discusses the temporal fit of teams of controllers to a real world hydropower system (HPS) in a deregulated market environment, emphasizing how well displays support quality of control performance by industry controllers. The results of an empirical evaluation suggest that displays that integrate task constraints over appropriate time scales help controllers construct more immediate ...
