Abstract
This paper presents an algorithm for determining an economical operation and introduction schedules of dispersed cogeneration sources in electric power systems considering energy storage systems (ESS). Generally, it is considered that ESS plays some important roles. More specifically, it works as a buffer for regulating the time gap between electric load and thermal load, and also as alternative peaking units. First, this paper defines an index for representing a possibility for introduction of the ESS considering thermal merits of FC system. Using this index, we can determine the optimal operation of the FC system including the ESS. Further, this paper develops an algorithm for determining generation mix considering both FC system and ESS. In this method, the whole generation mix problem is decomposed into two subproblems, i.e., an generation mix problem for generators and FC system and an operation problem of ESS, and each subproblem is solved successively.
