چکیده مقاله:

In deregulated electricity markets, market participants (producers and consumers) are mainly allowed to makebilateral financial contracts to protect themselves against the fluctuations of the locational marginal prices (LMP) or nodal prices. In a network including a large number of the producers (generators) and consumers (loads), it is difficult for consumers to find the best bilateral financial contract to maximize their revenue. This paper addresses a mathematical decision making system to determine the best bilateral financial contract for consumers. The proposed decision making system is presented in two levels as master and slave levels. In slave level, all consumers maximize their revenue and submit their individual plans to the master level. In master level, the network constraints (i.e. technical and financial constraints) are checked and verified by independent system operator (ISO). If the network constraints are violated, ISO will send new price signals to the slave level for consumers’ rescheduling. It is an iterative procedure between slave and master levels for simulating the interactions between consumers and ISO. The proposed method is mathematically expressed as a nonlinear, constrained problem and solved using particle swarm optimization (PSO) algorithms. Simulation results demonstrate that the proposed mathematical decision making system can successfully help the consumers to select the best bilateral financial contract with the purpose to maximize their revenue.
