This paper proposes a novel technique for representing system security in the operations of decentralized electricity markets, with special emphasis on voltage stability. An Interior Point Method is used to solve the Optimal Power Flow problem with a multi-objective function for maximizing both social benefit and the distance to maximum loading conditions. A 6-bus system with both supply and de...

We consider a novel paradigm for demand side management that is based on the so called fuse control concept. We assume that an aggregator communicates with a household only at the meter, imposing a fuse limit, i.e. a restriction on the total consumption level within a given time frame. Consumers are then responsible to adjust the set-points of the individual household devices accordingly to mee...

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...

The proliferation of online auctions has attracted significant research interest in understanding real-life bidding behavior. However, most of the empirical work has focused on business-to-consumer (B2C) auctions. A natural question is whether the findings obtained from B2C auctions are applicable to business-to-business (B2B) auctions which often involve much higher stakes. In this paper, we e...

We present a fast and effective bidding strategy for the Trading Agent Competition in Supply Chain Management (TAC SCM). In TAC SCM, manufacturers compete to procure computer parts from suppliers, and then sell assembled computers to customers in reverse auctions. To address the bidding problem, an agent decides how many computers to sell and at what prices to sell them. We propose a greedy sol...

This paper mainly discusses the demand bidding and risk management of user aggregators by considering profit risk. The covariance matrix price was used to analyze model under an uncertain price. By revenue cost, strategy derived obtain maximum profit. using a risk-tolerance parameter β, new for that takes both into consideration formulated. We simulated posed fluctuating prices this model. Fina...

Demand-side management is a resilient concept [...]

The active participation of demand-side flexible resources in the wholesale market price formation and load dispatch process is crucial to encouraging participation. This calls for a joint supply-demand coordination mechanism fully take advantage distribution systems, including distributed energy (DERs) responsive loads (RLs). paper aims at comparing evaluating centralized transactive distribut...

With the onset of large numbers of energy-flexible appliances, in particular plug-in electric and hybrid-electric vehicles, a significant portion of electricity demand will be somewhat flexible and accordingly may be responsive to changes in electricity prices. In the future, this increased degree of demand flexibility (and the onset of only short-term predictable intermittent renewable supply)...
