High penetration of distributed energy resources raises operational and market challenges. Existing incentives and tariff support can not be sustained with penetration growth and competitive market mechanisms are required at the micorgrid level. We propose a market mechanism to bring competitiveness at the microgrid level. In this dynamic matching mechanism, individual generators and load units meet...
The present deregulated electricity industry has evolved into a distributed and competitive industry in which market forces drive the price of electricity and reduce the net cost of electricity. However the competitions in these markets require identification of the use of transmission networks, mainly the participation of utilities in losses caused in the transmission lines. This is because the consumers...
In a competitive electricity market Generating Companies or suppliers participate in the bidding process in order to get maximum profit. Therefore, each supplier will bid strategically for choosing the bidding coefficients to counter the competitors bidding strategy. In this paper bidding strategy problem is modeled as an optimization problem and solved using a novel algorithm based on Differential...
One of the main objectives of deregulation has been to achieve more efficient power systems. Exercise of market power can significantly increase prices in the power market thereby reducing the efficiency. This makes it important for regulatory bodies to survey and intervene if the market is malfunctioning. In hydropower systems this is extra difficult to reveal because the resource for the supply...
The deregulation of the electrical power industries has opened many opportunities to power buyers, once price takers of a monopolistic economy, to look forward to a free market economy with market forces determining the market clearing prices and quantities. However, the strong influence of technical and physical constraints of the network may result in economic decisions that adversely affect the...
Game Theory is a long standing method of analysing the way in which participants interact within a market space, recently agent based approaches have been utilised to understand even more about these interactions. This agent based approach can be utilised to understand very complex market designs, such as those for an electricity market, with there being potential room for identifying potential problems...
The growth of electricity markets and evolution of electricity utility systems around the world towards a competitive environment have aroused considerable interest in the investigation of mechanisms for trading electricity, especially in such an environment that participants compete in both spot market bidding and bilateral contract trading. Equilibrium models using a Conjectural Variation (CV) approach...
In the deregulated power systems, the interruptible load management (ILM) is widely used as an effective measure to ensure reliability and mitigate the market price spike. A critical issue is the incentive paid to the consumers to participate in the ILM. This paper addresses the quantification and allocation of ILM's benefit from mitigating the wholesale price spike. This benefit is calculated within...
Fixed demands for electricity are incorporated into a game theoretic model of strategic generators who are supplied by a fuel transportation network and produce power for a congested electricity transportation network governed by an independent system operator. Some counter-intuitive effects on measures of market power result from reducing the proportion of demands that are fixed rather than price-sensitive...
In the environment of electricity market , the reflection of reserve on the reliability of electrical system is very visibly and reserve has couple with the main energy market. It seems very important to research equilibrium relationship of reserve market. The text presents a model that on the condition of opportunity cost and price elasticity of demand, formulates a model of the reserve equilibrium...
This paper describes a simple method to derive strategic equilibrium solutions for a single Generating Company (GENCO) bidding in electricity markets. This method computes the product mix of real power and the ancillary services of reactive power and spinning reserve supplied by GENCO. Generator capability curves are incorporated into a two-player competitive market model to simulate market auctions...
