Alternative Models of Restructured Electricity Systems, Part 1: No Market Power

Alternative Models of Restructured Electricity Systems, Part 1: No Market Power

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...

Variational Inequality Models of Restructured Electricity Systems

Market Power and Price Volatility in Restructured Markets for Electricity

The restructured market for electricity in the UK has experienced a systematic pattern of price spikes associated with the use of market power by the two dominant generators. Partly in response to this problem, the share of capacity owned by any individual generator after restructuring was limited in Victoria, Australia. As a result, a much more competitive market resulted with prices substanti...

How well can one measure market power in restructured electricity systems ? ∗

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...

a new framework for capacity market in restructured power systems

in order to improve the reliability of the power system, sufficient amount of new capacity should be installed in the network. usually generation units’ payoff in an energy market is not adequate to cover their expenses. therefore, energy only market cannot induce investors to invest in generation field. due to energy only market inefficiency, a supplementary algorithm is suggested to cover the...
