independent power producer parallel operation modeling in transient network simulations for interconnected distributed generation studies

 

the main task in this paper is to present a performance analysis of a distribution network in the presence of an independent power producer (ip) synchronous generator with its speed governor and voltage regulator modeled using tacs – transient analysis of control systems, for distributed generation studies. regulators were implemented through their transfer functions in the s domain. however, since atp-emtp (electromagnetic transient program) works in the time domain, a discretization is necessary to return the tacs output to time domain. it must be highlighted that this generator is driven by a steam turbine, and the whole system with regulators and the equivalent of the power authority system at the common coupling point (ccp) are modeled in the “atp-emtp – alternative transients program”.
