New control method for distribution network distributed static series compensator

This paper presents a new control method developed to enhance the performance of distributed static series compensator (DSSC) employed as a FACTS device on an 11KV distribution line. The new feedback based control strategy, based on the calculation of instantaneous power flows, is used to grantee an orthogonal injected voltage with respect to the line current while minimizing the exchange of active power between the DSSC device and the power system.
