The general power flow algorithm incorporating HVDC system can not consider the diversified control mode of HVDC system. Especially in Power System Analysis Software Package (PSASP), the key control parameters of HVDC are definite, which is to the disadvantage of steady state analysis and actual control of HVDC system. In this paper the control method transformation conditions and dealing strategies...
Misbalance between reactive power production and consumption in power system causes the variation of node voltage outside the proposed limit. It is a main task for system operators to maintain the voltage profile against any unexpected disturbance. In this paper a practical coordinated secondary voltage control (CSVC) scheme was present, which was based on the optimal power flow algorithm. Additional...
This paper presents a reliable algorithm for OPF calculation with UPFC control needs. Different UPFC control pattern for different optimal power flow calculation needs was present and analyzed. In each control pattern, only one parameter of UPFC series component is introduced and in these cases the gradient based OPF algorithm has a good performance similar to the cases without UPFC control. UPFC...
