Equilibrium price in intraday electricity markets

Investment in Electricity Markets: Equilibrium Price and Supply Function

In most real options models for evaluating power plants, it is assumed that the price fluctuates stochastically such as a geometric Brownian motion. In actual electricity market, the prices are determined by supply and demand, and the supply and demand balance may cause the price spike. Especially, the supply characteristics, which depend on the type and number of power plants in electricity ma...

Intraday Empirical Analysis of Electricity Price Behaviour

This paper proposes an approach to the intraday analysis of the dynamics of electricity prices. The growth optimal portfolio (GOP) is used as a reference unit in a continuous financial electricity price model. A diversified global portfolio in the form a market capitalisation weighted index approximates the GOP. The GOP, measured in units of electricity, is normalised and then modelled as a tim...

Equilibrium in Wholesale Electricity Markets

We develop game theoretic models to evaluate strategic behavior in deregulated electricity markets, with particular attention given to the market rules in place in California through the summer of 2000. We prove existence of a Nash equilibrium under two particular sets of market rules used by the CALPX and CAISO respectively. Next we derive a lower bound (strictly above marginal cost) on averag...

Intraday price dynamics in spot and derivatives markets

This study examines intraday relationships among the spot index, index futures, and the implied volatility index based on the VAR(1)-asymmetric BEKK-MGARCH model. Analysis of a high-frequency dataset from theKorean financialmarket confirms that there is a strong intraday market linkage between the spot index, KOSPI200 futures, and VKOSPI and that asymmetric volatility behaviour is clearly prese...
