Modeling the impact of multi-energy players on electricity market in smart grid environment

Future energy system is highly integrated system from both energy carriers and decision making points of view. In such a system, a multi energy player (MEP) is defined as an energy player who can convert and store a set of energy carriers. These players consist of local energy resources and behave as both consumer and producer in individual energy markets. As a matter of fact, MEPs are links among energy markets and enhance total flexibility of multi-energy system (MES). With increasing the share of MEPs in electricity market, their operational flexibility can affect market variables. In this paper, at first the behavior of a typical MEP is modeled in electricity market. After that the share of MEP in electricity market is increased to survey its impact on electricity market interactions. Moreover, the impact of MEP's gas contract on its behavior in electricity market is investigated. The numerical results illustrate the impact of these factors on electricity market parameters.
