How to effectively evaluate price of volatility risk is the basis of risk management in electricity market. Electricity price connotes a grey system, due to uncertainty and incomplete information for partial external or inner parameters. A two-stage model for estimating value-at-risk based on grey system and extreme value theory is proposed. Firstly, in order to capture the dependencies, season...

Organized trading for electricity includes both the pool and the futures market. Pool prices are volatile while the prices of the futures-market products are comparatively more stable. Thus, futures-market products constitute hedging instruments to reduce the risk suffered by any market agent. Electricity market agents engage in both pool and futures market transactions seeking to maximize thei...

By increasing the extraction of natural gas, its role in the restructured power systems is being expanded, due to its lower pollution. Iran has the second largest reserves of natural gas in the world and exports it to different countries. This paper represents long run analysis of natural gas export from Iran to Turkey as a case study, considering direct transfer and exporting via the power mar...

Electricity markets face a substantial amount of uncertainty. While traditionally this uncertainty has been due to varying demand, with the integration of larger proportions of volatile renewable energy, added uncertainty from generation must also be faced. Conventional electricity market designs cope with uncertainty by running two markets: a market that is cleared ahead of time, followed by a...

A major concern in the design of wholesale electricity markets is the potential for the exercise of market power by generating unit owners. To better understand the determinants of generating unit owner market power and how it is exercised, this paper derives a model of bidding behavior in a competitive electricity market which incorporates various sources of uncertainty and the impact of the e...

Due to exposure to uncertainty created by the deregulation of electricity industries worldwide and the need to respond to climate change via investment in more sustainable technologies, the challenges and opportunities facing power companies have increased over the past decade. Consequently, the electric power sector requires decision support that is more responsive to market conditions, while ...

This paper examines how actors in the UK electricity sector are attempting to deliver investment in low carbon generation. Low carbon technologies, because of their relative immaturity, capital intensity and low operational costs, do not readily fit with existing electricity markets and investment templates which were designed for fossil fuel based energy. We analyse key electricity market and ...

In this paper, we study how datacenter energy cost can be effectively reduced in the wholesale electricity market via cooperative power procurement. Intuitively, by aggregating workloads and renewables across a group of datacenters, the overall power demand uncertainty of datacenters can be reduced, resulting in less chance of being penalized when participating in the wholesale electricity mark...
