Although many countries prefer deregulated power markets as a means of containing costs, monopoly may still exist. In this study, an agent-based bidding simulation framework is proposed to detect whether there will be in the market. A security-constrained unit commitment (SCUC) conducted clear Using characteristics that agent can fully explore certain environment and Q-learning algorithm, each ...

This paper proposes a pricing system for power system security in deregulated electricity market that includes voltage stability constraint in a multi-objective OPF problem. The OPF maximizes social benefit, as well as the distance from the voltage-collapse point. While pricing system security, ancillary service such as reactive power has been included. Effect of N–1 contingency on pricing is a...

Electricity generators in most deregulated markets simultaneously operate in both financial (contract) and physical (spot) markets. Decisions in each of these markets are not mutually exclusive, and in the case of imperfectly competitive scenarios generating companies can use their market power to influence spot and contract prices. A model of oligopolistic market equilibrium is presented where...

This paper proposes an Artificial Bee Colony (ABC) algorithm to Generator Maintenance Scheduling (GMS) in competitive market. In the regulated market the problem of generating optimal maintenance schedules of generating units for the purpose of maximizing economic benefits and improving reliable operation of a power system, subject to satisfying system constraints. In case of deregulated market...

This paper examines the former wholly government owned telecommunication company (TelCo), the Telecom Corporation of New Zealand (TCNZ), that was privatised in 1989 and induced to compete in a deregulated operating environment as the New Zealand government moved to open up its telecommunications’ sector to competition. In broad terms this paper examines the organisational and workforce restruct...

This paper examines the impact of government guaranteed small business loans on economic growth, and whether government guaranteed loans crowd out new businesses financed through the market. OLS estimates indicate a significant and positive relation between the Small Business Administration’s (SBA) guaranteed loans and metropolitan growth between 1993 and 2002. However, endogeneity hinders caus...

This paper proposes a multi-timescale coordinated operation approach which coordinates the combined heat and power (CHP) plant wind farm in deregulated day-ahead market real-time balancing electricity market. aims to optimize profits of CHP-wind portfolio by considering energy sale penalty two-price Multiple uncertainties load, generation, price, up- down-regulation prices are taken into accoun...

The investment problem faced by producers in deregulated electricity markets contains high uncertainties about the future. It can also be seen as a game, as only a small number of large players act in the market. A dynamic stochastic oligopoly model to describe the production and investment in such a situation is developed and applied to the Finnish electricity market. The demand growth rate is...

This paper studies a supply chain consisting of two suppliers and one retailer in a spot market, where the retailer uses the newsvendor solution as its purchase policy, and suppliers compete for the retailer’s purchase. Since each supplier’s bidding strategy affects the other’s profit, a game theory approach is used to identify optimal bidding strategies. We prove the existence and uniqueness o...
