The integration of national electricity systems into a single internal European electricity market is not progressing well with the result that the level of competition in the sector remains unsatisfactory. This had led to proposals to apply ex ante remedies that directly bear on the structure of national incumbents. These measures involve quantitative recommendations such as virtual auctioning...

Electric power industries throughout the world have been restructured to introduce competition among the market participants and bring several competitive opportunities. Open access to the transmission system places an emphasis on the intensive use of the interconnected network reliably, which requires knowledge of the network capability. Available Transfer Capability (ATC) is a measure of the ...

Different equilibrium concepts have been proposed by various authors (Schweppe et al, Hogan, Chao and Peck, Wu et al) to analyse competitive electricity systems. We establish correspondences between these different models though a single framework and provide additional interpretations of these equilibrium concepts. This unifying conceptual view also provides a computationally feasible approach...

The National Electricity Market is the centerpiece of the Australian restructured electricity industry. It is a spot market in which prices are determined on a five-minute basis but half-hour averages are used for commercial transactions. The five-minute prices are broadcast to participants so that the can respond while the prices are still avoidable. An approximate form of nodal pricing is

In a deregulated electricity market, it may always not be possible to dispatch all of the contracted power transactions due to congestion of the transmission corridors. This paper presents a transmission lines congestion management in a restructured market environment using a combination of demand response and Thyristor controlled series compensators (TCSCs). The overall objective of FACTS devi...

In this paper we discuss the problem of power generation capacity adequacy in restructured and competitive power systems and analyse potential regulatory mechanisms to ensure sufficient supply of electricity. In particular, we look at how uncertainty influences the optimal timing of investments in new power generation capacity. We formulate the power generation investment problem for a decentra...

This study uses dynamic 5-bus and 30-bus test cases to explore the net surplus (congestion rents) collected and redistributed by ISOs in restructured wholesale power markets with grid congestion managed by locational marginal pricing. The price-sensitivity of demand and the learning capabilities of generators are taken as treatment factors. A key finding is that ISO net surplus substantially in...

In power systems that are restructured on the basis of system reliability or the costs, various methods can be employed for allocating the spinning reserve to various generating units. This paper firstly describes two methods for allocation of reserve power: (1) a cost-based method; (2) a reliability-based method. Secondly, presents a combined method that simultaneously considers both reliabili...

As the electricity industry in California undergoes a process of fundamental restructuring, important new products and markets will be created while others will lose signi cance. In this paper, we make an initial survey of the products and markets that will be prominent in the emerging new electricity industry. We describe approaches to analyzing the prospects for, and the impacts of, market po...
