Control inteligente de frecuencia en sistemas con baja inercia basados en sistemas de almacenamiento de energía con superconductores magnéticos.

Abstract

This job presents a methodology for frequency regulation in electrical power systems through a coordinated intelligent control of superconducting magnetic energy storage systems (SMES). For this, a phasor model of an SMES system and a control with fuzzy logic are proposed. Through virtual PMUs, the frequency measurements are obtained which are used to calculate the average RoCoF and later, this value enters to the fuzzy control to establish the coordination of the SMES systems. To evaluate the performance of the SMES system model and the proposed coordinated control, the SMES systems are integrated into the IEEE New England 39-bus test network and a hybrid network of the same, which integrates wind and photovoltaic generation. The test network is subjected to power disturbances. The contribution SMES systems in inertial control, primary and secondary frequency control are analyzed. For this, frequency parameters such as nadir, zenith and RoCoF are verified. A contrast is made of the effect of reducing inertia in the network, and it is analyzed how SMES systems contribute to frequency regulation in this case.
