3.4.2 „Agent-based simulation for the Germ<strong>an</strong> electricity markets -<br />
An <strong>an</strong>alysis <strong>of</strong> the Germ<strong>an</strong> spot market prices in the year<br />
2001“<br />

The Germ<strong>an</strong> electricity sector has undergone considerable ch<strong>an</strong>ges throughout the past few years.<br />
Main developments are the liberalisation <strong>of</strong> electricity markets, the evolving Europe<strong>an</strong> CO 2 emissions<br />
trading scheme <strong>an</strong>d the promotion <strong>of</strong> renewable electricity generation. Policy makers <strong>an</strong>d market<br />
players have to deal with new aspects like market power, bounded rationality <strong>an</strong>d the appear<strong>an</strong>ce <strong>of</strong><br />
fluctuating energy sources. In the given environment the complex interactions between different<br />
markets <strong>an</strong>d environmental policy instruments like CO 2 emission trading become <strong>an</strong> issue <strong>of</strong><br />
increasing import<strong>an</strong>ce. A promising <strong>an</strong>d novel approach for the scientific <strong>an</strong>alysis <strong>of</strong> these new<br />
developments is the field <strong>of</strong> agent-based simulation. This paper presents a first version <strong>of</strong> the agentbased<br />
simulation platform PowerACE for the simulation <strong>of</strong> the Germ<strong>an</strong> electricity sector. In a case<br />
study the PowerACE model is used to simulate the development <strong>of</strong> market prices on the Germ<strong>an</strong> spot<br />
market in the year 2001. In order to <strong>an</strong>alyse the capabilities <strong>of</strong> the model the results are compared to<br />
the <strong>of</strong>ficial spot market results <strong>of</strong> the LPX (EEX) in the year 2001. In a second step <strong>an</strong> algorithm for the<br />
integration <strong>of</strong> start-up cost is presented <strong>an</strong>d applied to the simulation.<br />
The PowerACE simulation platform simulates import<strong>an</strong>t players within the electricity sector as<br />
computational agents. Among these are agents representing consumers, utilities, renewable agents,<br />
grid operators, government agents <strong>an</strong>d market operators. Some players like utilities are simulated<br />
using several computational agents representing different functions within the comp<strong>an</strong>y like trading or<br />
generation. An overview <strong>of</strong> the main agents involved in the simulation is given in<br />

In general the simulation platform c<strong>an</strong> be categorized in four modules dealing with markets, electricity<br />
dem<strong>an</strong>d, utilities <strong>an</strong>d renewable electricity generation. This paper seeks to <strong>an</strong>alyse the capability <strong>of</strong><br />
the model to simulate spot market prices in order to provide <strong>an</strong> adequate basis for future <strong>an</strong>alysis.<br />
Therefore a central part <strong>of</strong> the simulation is to provide realistic data on the electricity dem<strong>an</strong>d,<br />
