A new model to deal with the short-term generation scheduling problem for hydrothermal systems is proposed. Using genetic algorithms (GAs), handles simultaneously subproblems of coordination, unit commitment, and economic load dispatch. Considering a horizon period week, hourly schedules are obtained each both hydro thermal units. Future cost curves generation, from long mid-term models, have been used optimize amount energy be during week. In algorithm (GA) implementation, technique...

The allocation of costs a transmission system to its users is still pending problem in many electric sector market regulations. This paper contributes with new method among the participants. Both cooperation and competition are defined as leading principles fair solutions efficient cost allocation. based mainly on responsibility agents physical economic use network, their rational behavior, formation coalitions, cooperative game theory resolution mechanisms. designed applicable existing...

Although extreme events, mainly natural disasters and climate change-driven severe weather, are the result of naturally occurring processes, power system planners, regulators, policy makers do not usually recognize them within network reliability standards. Instead, planners have historically designed electric infrastructure accounting for so-called credible (or "average") outages that represent single or (some kind of) simultaneous faults (e.g., on double circuits).

Countries around the world suffer dramatic impact of earthquakes and other natural hazards reflected in casualties, infrastructure damage, service interruptions, recovery costs. Although disaster exposure consciousness electric power systems has increased recent years, mitigation adaptation actions, such as reserve scheduling investments, are usually performed without quantitative tools to account for underlying stochasticity these events. This article first discusses why an integrated...

There are two approaches to the mitigation of power quality problems. The first approach is called load conditioning, which ensures that equipment made less sensitive disturbances, allowing operation even under significant voltage distortion. other solution install line-conditioning systems suppress or counteract system disturbances. Among different new technical options available improve quality, active filters have proved be an important and flexible alternative compensate for current...

Although extreme natural disasters have occurred all over the world throughout history, power systems planners do not usually recognize them within network investment methodologies. Moreover, had historically focused on reliability approaches based average (rather than risk) performance indicators, undermining effects of high impact and low probability events decisions. To move towards a resilience centred approach, we propose practical framework that can be used to identify investments...

This paper is the first of two and presents a planning methodology for low-voltage distribution networks. Combined optimization transformers associated networks performed, considering street layout which connects different consumers. In this part, micro-optimization, zone divided into small zones, mini-zones, are optimized independently. A repetitive procedure used in order to locate using clustering techniques. Optimum capacity, customers be satisfied, optimum network losses determined each...

This article contributes to the discussion by assessing some general market and economic impacts of renewable generation in electricity markets Spain, Germany Latin America. The need diversify away from fossil fuel due concerns over energy security, price volatility, climate challenge is driving deployment nonconventional (wind, small hydro, solar, tidal, geothermal, cases waste) or "green" worldwide.

A dynamic transmission planning methodology using a genetic algorithm is formulated for the purpose of determining an economically adapted electric system in deregulated open access environment. Transmission investment sensitivity information linked to short term marginal income used. computer program developed and applied obtain long range grid Chilean electrical system. Two pricing methodologies are evaluated spot price framework, as over time horizon.

The disadvantages of traditional "rate return" regulation for distribution tariffs have led to he development new regulatory schemes stimulate efficiency in the provision service, under what has been called "benchmark regulation". paper assesses Chilean "model company" that aims at making private monopoly compete with a reference efficient model company, through "yardstick competition" approach. It compares it "price cap" scheme used electricity England and Wales. contributes proposal...

The paper defines and classifies essential issues that relate the need for electric power system coordination with increasing development of competition. Principles are formulated a model market structure proposed, emphasizing economic dispatch in wholesale market. A detailed comparison is made pooling implementations developed Argentina Chile, countries have pioneered creation competitive markets energy sector. An evaluation strengths weaknesses those two included.

This paper is the second of two and presents a planning methodology for low-voltage distribution network planning. Combined optimization transformers associated networks applied, considering street layout which connects different consumers. In first section, zone division into smaller mini-zones performed; zones are optimized independently. section develops macro-optimization methodologies that use results techniques previous stage, allow performing global analysis zone.

Security of energy supply is a main concern worldwide, given the strong dependence on society functioning its adequate delivery. Surges in fuel prices, political conflicts, wars and natural disasters threaten directly supply, countries look at ways to protect themselves.

A method is presented that allows finding the market clearance prices within a hydrothermal power exchange incorporates network constraints. An analysis made of degree exerted by various agents. The Nash-Cournot equilibrium solution achieved using Nikaido-Isoda function, which derived from profit maximization functions calculated generating companies. Both thermal, hydro generation, and constraints are considered in model, with coupling units also taken into account. model applied to main...

The pioneering restructuring and deregulation process of the electricity industry, which started in Latin America as early 1982, is assessed. Chile Argentina, among others, have been at forefront innovation creation markets. experience gained principal difficulties encountered these 18 years are reviewed, highlighting weaknesses successes processes. A review made challenges prospects for development electrical sector region, where energy integration across countries flourishes world players...
