Comparative Assessment of SVC and TCSC Controllers on the Small Signal Stability Margin of a Power System Incorporating Intermittent Wind Power Generation

Table 6

Order of performance of the controller(s) at damping electromechanical modes.

S/N	Controllers and possible combination	Order of performance
1	SVC + PSS	1st
2	TCSC + PSS	2nd
3	Probabilistic allocation of PSS only	3rd
4	SCV only	4th
5	Deterministic allocation of PSS only	5th
6	TCSC only	6th
