Several regions of the U.S. have sought to restructure the electric power industry by separating the potentially competitive generation sector from the natural monopoly functions of electricity transmission and distribution. Under this restructuring scheme, a central authority, which we will refer to as the independent system operator (ISO), is given control over both the transmission system an...

The modern trend in electricity industries around the world is towards increasing competition through deregulation and privatisation. For example, movement towards one large EU-wide market began in 1996 with EU Directive 96/92, which sets out common rules and targets concerning competition, unbundling and transparency. However, the particular nature of electricity generation and supply means so...

multistage stochastic programming is a key technology for making decisions over time in an uncertain environment. one of the promising areas in which this technology is implementable, is medium term planning of electricity production and trading where decision makers are typically faced with uncertain parameters (such as future demands and market prices) that can be described by stochastic proc...

This paper presents estimates of the customer-level demand for electricity by industrial and commercial customers purchasing electricity according to the half-hourly energy prices from the England and Wales (E&W) electricity market. These customers also face the possibility of a demand charge on its electricity consumption during the three half-hour periods that are coincident with E&W system p...

The growth and expansion of economic concepts in the power system is increasing in last years. Energy economists have considered the optimal decision-making of electricity market retailers in recent years. In this paper, a demand response program based model is pro-posed in order to make the optimal decision of the retailer in the electricity market, taking into account the different conditions...

a r t i c l e i n f o Keywords: Hurst exponent Nonlinear dynamics Chaos Offer behavior Locational marginal price (LMP) In electricity markets where supply and demand drives the price for the purchase and sale of electricity, generating firms change capacity for various reasons including load level, policy, and varying market conditions. These types of fluctuating production patterns can result ...

Traditional management of electricity portfolios is focused on the day-ahead market and futures of longer maturity. Market participants use these markets to trade any excess production or consumption in their portfolio and balance their total position. Within limits, market participants can also resort to the balancing energy market to close their positions. The energy transactions on the balan...

A major concern in the design of wholesale electricity markets is the potential for the exercise of market power by generating unit owners. To better understand the determinants of generating unit owner market power and how it is exercised, this paper derives a model of bidding behavior in a competitive electricity market which incorporates various sources of uncertainty and the impact of the e...

The paper adopts the Conjectural Variation model for investigating firms’ strategic behaviors in the wholesale electricity market. The aim of the proposed approach is providing market actors with a tool able to simulate the oligopolistic market models. The tool, utilized by a Generating Company (GenCo), permits to foresee the rivals’ behaviors and builds the suitable supply bid curve for its ow...
