Abstract:
The main goal of this paper is to modeling of producers’ strategic
suggestions for each electricity manufacturer in an oligopolistic
structure. According to the proposed structure of the electricity
market modeling; this paper uses a dynamic model based on
cournot equilibrium. Due to the large volume of required
information, the implementation of the model is limited to a
regional electricity market and the model is be implemented in such
as a way to compare the results for low, medium and peak load
consumption. Market actors in the research are active power plants
in Isfahan electricity region and MATLAB software has been used
for solving the model. The empirical results of model with the
actual behavior of actors in selected hours have been compared and
finally by comparing the actual behavior of actors with the results
of the simulation model, the analysis and results are presented.
Accordingly it is clear that the producers did not use cournot
strategy. Although the proposed strategy can be more profitable for
them.
Machine summary:
"From the producer point of view the presented modeling in this study is exactly manufacturer’s bidding strategy with respect to cost of production, the quantity demanded in the market in every market executive and the behavior of other actors.
In other words, expected simulation in the study provides plants optimizing production in an electricity market and from the social perspective of the model made it possible to analyze the behavior of market actors as well as market stability in Iranian power market.
Due to this property that electrical energy is not saving at any given time the amount of production and consumption must be equal and the equality of supply and demand is as follow: (View the image of this page)i=1 According to the stated elements the profit of each plant which is obtained by subduction of the cost of revenue is as follow: (View the image of this page)To find the maximum amount of earnings we derived it from the Profit function and define the zero of derivative function: (View the image of this page)This process is performed for one round and adjustment factor is used for next round.
Tests for Power Plants Cost Functions (View the image of this page) In table 4 the stability of different demand functions were tested and the results obtained based on stationary variables.
The Results of Cournot Solution for a Base Day (View the image of this page)In Table 8 production values at each plant are separately achieved by using baseline values in the previous section and the adjustment coefficients."
