Electricity market players operating in a liberalized environment requires access to an adequate decision support tool, allowing them to consider all the business opportunities and take strategic decisions. Ancillary services represent a good negotiation opportunity that must be considered by market players. For this, decision support tools must include ancillary market simulation. This paper proposes...

Aiming at the risk management that electricity purchasers will face in power purchase of four markets under the framework of the electricity market, two purchasing electricity models about the restrictions or non-restriction are set up by means of Variance measuring risk. Meanwhile, this paper also proposes several feasible algorithms to minimize risks, including statistical genetic algorithms (SGA)...
Electricity market price may not always be a reference to determine the existence of market power. This paper discusses why electricity price in a day-ahead electricity market may exhibit peaks without representing market manipulation by any of the players. We use genetic algorithms to simulate the trading behavior of artificial agents in the spot market. Two case studies are reported and the results...
Power systems operation in a liberalized environment requires that market players have access to adequate decision support tool, allowing them to consider all the business opportunities and take strategic decisions. Ancillary services represent a good negotiation opportunity that must be considered by market players. For this, decision support tools must include ancillary market simulation. This paper...
The main benefit of implementing interruptible load (IL) management for power suppliers is from the impacts of the level of demand for electricity on spot prices. In terms of conditional value at risk as the measuring index for market risk, a model of load curtailing strategies for power suppliers considering the co-utilization of the IL with low price (ILL) and the IL with high compensation price...
Aiming at the choices and risk management that electricity purchasers will face to purchase power in four markets under the framework of the electricity market. This paper, which uses semi-variance to measure risk, has established two risk decision-making models based on restrictive and non-restrictive buy/sell through risks measured by semi-variance. Meanwhile, it proposes to minimize the risks on...
Market power is one of the main concerns in the Italian electricity market. Transmission constraints and highly concentrated ownership structure in the market have been allowing firms to exercise market power and raise electricity prices above marginal cost. This paper presents a supply function equilibrium (SFE) model for analyzing the exercise of potential market power in the Italian electricity...
Long-term demand forecasting presents the first step in planning and developing future generation, transmission and distribution facilities. One of the primary tasks of an electric utility accurately predicts load demand requirements at all times, especially for long-term. Based on the outcome of such forecasts, utilities coordinate their resources to meet the forecasted demand using a least-cost...
