Experiences with operations of power markets show that contracts may affect stability of markets. Therefore, it is necessary to consider whether the market with bilateral contracts will lead to a stable equilibrium conditions after the market is exposed to certain kinds of disturbances. In this paper, the dynamic behaviour of power markets is expressed by differential/algebraic equations, and eigenvalue analysis is used to study effects of contracts on stability of the model. Results of the analysis show that suitable relative ratio of contracts can improve the stability of power markets and even make the unstable markets stable. On the other hand, unsuitable relative ratio of contracts may deteriorate the stability of markets.
