This paper proposes a methodology that allows modeling the behavior of power flows in transmission systems through synchrophasors. Firstly, is propose a problem of optimal location of PMUs solved by mixed integer programming (MIP) is proposed to obtain a complete observability of the system by means of synchrophasors, afterwards an AC power flow is solved through non-linear programming (NLP), to determine the voltages and nominal powers in the observation nodes.. The load characteristics of the observed nodes are modeled in active and reactive power components in the observation node using the ZIP load model. The load model coefficients are estimated to pose a least squares problem that is solved by nonlinear programming (NLP) and finally the power flow behavior is determined by the analysis of the phase angles between the observation node and the observed nodes. The methodology is tested in IEEE 9, 14 and 30-bus system. |
