Optimal Hydropower Maintenance Scheduling in Liberalized Markets

Optimal Operation of Combined Heat and Power Based Power Systems in Liberalized Power Markets

Modelling generator maintenance scheduling costs in deregulated power markets

Generating companies use the maintenance cost function as the sole or main objective for creating the maintenance schedule of power generators. Usually only maintenance activities related costs are considered to derive the cost function. However, in deregulated markets, maintenance related costs alone do not represent the full costs of generators. This paper models various cost components that ...

Game-theory-based generation maintenance scheduling in electricity markets

This paper presents a novel approach to the (generation maintenance scheduling) GMS problem in electricity markets. The main contribution of this study is the modeling of a coordination procedure for an (independent system operator) ISO, based on a game-theoretic framework for the GMS problem. The GMS process of generation companies (Gencos) is designed as a non-cooperative dynamic game, and th...

Reducing Operating Costs with Optimal Maintenance Scheduling

The potential benefits of optimal service scheduling for cleaning heat exchangers based on minimizing operating costs are explored. A demonstration is performed on a simulated 20 ton air-to-air vapor compression air conditioner. The costs of regular service schedules (indicative of current practice), minimal schedules needed to maintain comfort, and the optimal schedules are compared. Generally...

Multi-Stage Stochastic Electricity Portfolio Optimization in Liberalized Energy Markets

In this paper we analyze the electricity portfolio problem of a big consumer in a multi-stage stochastic programming framework. Stochasticity enters the model via the uncertain spot price process and is represented by a scenario tree. The decision that has to be taken is how much energy should be bought in advance, and how large the exposition to the uncertain spot market, as well as the relati...
