In this paper the problem of modeling electricity price dynamics in deregulated energy markets is studied. Since the nature of customers' energy consumption, market participants' strategic behavior and the power system reliability indices are stochastic processes, the electricity price model will be stochastic as well. In our analysis the price of electricity is modeled based on the customers' ...

The electricity market has changed rapidly in the Northern European countries. Harmonisation of the legislation and trading methods widens the market area outside national limits. Vertical integration among electricity companies is changing the traditional structure of the inner market. Successful business in this new, more volatile market requires sophisticated techniques for identifying new m...

The aim of this paper is to present impact studies of economic and environment related constraints on the German electricity spot market. The analysis was carried out using the system dynamics based model for the German electricity market, called “Zertsim”. The model was applied for the first time in a workshop with entrepreneurs from the region of Karlsruhe in Germany. One result of the worksh...

the paper tries to present an improved mathematical model for distribution companies (discos) in order to solve distribution network expansion planning (dnep) problems in the presence of certain resources of distributed generations (dgs) entitled small scale gas engines in the medium voltage grids. with the aim of minimizing investment and operation costs, the recommended model combines a compr...

This paper argues that the market rules governing the operation of a re-structured electricity market in combination with its market structure can have a substantial impact on behavior of marketclearing prices. Using evidence on the design of electricity markets in England and Wales, Norway, the state of Victoria in Australia and New Zealand, this paper illustrates that market structure and mar...

Generally the generation units in the traditional structure of the electricity industry try to minimize their costs. However, in a deregulated environment, generation units are looking to maximize their profits in a competitive power market. Optimum generation planning in such structure is urgent. This paper presents a new method of solving economic dispatch in the competitive electricity marke...

The purpose of this paper is to analyze the real–time trading of electricity. We address a model for an auction–like trading which captures key features of the real–world electricity markets. Our main result establishes that, under certain conditions, the expected total payment to the electricity producers is independent on particular auction type. This result is analogous to the revenue equiva...

Non-storability of a commodity implies the independence of corresponding spot and futures prices. We investigate empirically the case of electricity and show that a relation does emerge between spots and forwards. This is because of the links in storable fuels used for production and behavioural biases in power trading. The latter cause a significant influence of the electricity spot price on t...
