Transmission networks have some constraints that should be addressed in order to ensure sufficient control to maintain the security level of a power system while maximising market efficiency. The most obvious drawback of transmission constraints is a congestion problem that becomes an obstacle...

In electricity markets where competition has been established for a long time, a nuclear operator familiar with the operation of such markets could be interested in the optimal long-term management of a flexible nuclear set (like the French) in a competitive market. To obtain a long vision of...

The daily average price of electricity represents the price of electricity to be delivered over the full next day and serves as a key reference price in the electricity market. It is an aggregate that equals the average of hourly prices for delivery during each of the 24 individual hours. This...

In this paper, we build a realistic large-scale agent-based model of the Italian dayahead-electricity market based on a genetic algorithm and validated over several weeks of 2010, on the basis of exact historical data about supply, demand and network characteristics. A statistical analysis...

From auction theory we know that multi-unit, pay-as-bid auctions in general lead to bid shading and thus to an inefficient allocation. This result is supported by historical data from the German market for balancing power, which show that bidders bid well above their actual costs. In contrast to...

Reduction in energy dependancy and emissions of CO2 via renewables targeted in the European Union energy mix and taxation system might trigger the production of bioenergy production and competition for biomass utilization. Torrefied biomass could be used to produce second generation biofuels to...

In this paper, we analyze the influence of forward trading on the volatility of spot power prices, in models where forward contracts are strategic tools used by energy producers to obtain profit security. We define volatility as the variance of the percentage change in spot power prices over a...
