“…Brainstorm optimization algorithm (BSOA) was introduced to check the suitable position of TCSC and SVC devices to manage voltage profile and to reduce the active power losses [13]. In Reference [14], Hybrid immune algorithm (IGA and IPSO) was developed for optimal engagement of UPFC with the motivation of enhancing the power systems loading. These techniques were tested for IEEE 14 and IEEE 30 bus test networks.…”

Operation of power system within specified limits of voltage and frequency are the major concerns in power system stability studies. As power system is always prone to disturbances, which consequently affect the voltage instability and optimal power flow, and therefore risks the power systems stability and security. In this paper, a novel technique based on the "Artificial Algae Algorithm" (AAA) is introduced, to identify the optimal location and the parameters setting of Unified Power Flow Controller (UPFC) under N-1 contingency criterion. In the first part, we have carried out a contingency operation and ranking process for the most parlous lines outage contingencies while taking the transmission lines overloading (NOLL) and voltage violation of buses (NVVB) as a performance parameter (PP = NOLL + NVVB). As UPFC possesses too much prohibitive cost and larger size, its optimal location and size must be identified before the actual deployment. In the second part, we have applied a novel AAA technique to identify the optimal location and parameters setting of UPFC under the discovered contingencies. The simulations have been executed on IEEE 14 bus and 30 bus networks. The results reveals that the location of UPFC is significantly optimized using AAA technique, which has improved the stability and security of the power system by curtailing the overloaded transmission lines and limiting the voltage violations of buses.

Abstract-Accompanyingwith many flexible AC transmission system(FACTS) devices put into operation, the safety and reliability of power system operation have been suffering more serious influence and unprecedented challenge. Moreover, it's always difficult to comprehensively and accurately analyze the impacts of UPFC, the most versatile FACTS, on the operation characteristics of power system. This paper presents a framework for UPFC modeling based on the user-defined modeling (UDM) theory as well as a leading-edge stability analysis software named DSATools TM . Furthermore, the characteristics of steady-state and dynamic responses are compared and analyzed under the condition of two-machine system. Numerical results from various simulations verify the feasibility and effectiveness of the proposed UPFC in terms of both the independent regulation of power flow and the improvement of transient stability.

“…While in [18], an optimal strategy comprising CPF and OPF techniques to install the static model of UPFC, was proposed by minimizing the sum of the generation cost and investment. The hybrid immune algorithms (HIA) proposed in [19], with the performance validated to be better than other evolutionary methods such as GA, PSO, and IA, were utilized to increase system loadability by optimizing the locations for UPFC installation. The new indices, thermal capacity index (TCI) and contingency capacity index (CCI), proposed in [20] were used to place TCSC at appropriate location under normal and network contingency conditions respectively.…”

-Instead of building new substations or transmission lines, proper installation of flexible AC transmission systems (FACTS) devices can make the transmission networks accommodate more power transfers with less expansion cost. In this paper, the problem to maximize power system loadability by optimally installing two types of FACTS devices, namely static var compensator (SVC) and thyristor controlled series compensator (TCSC), is formulated as a mixed discrete-continuous nonlinear optimization problem (MDCP). To reduce the complexity of the problem, the locations suitable for SVC and TCSC installations are first investigated with tangent vector technique and real power flow performance index (PI) sensitivity factor and, with the specified locations for SVC and TCSC installations, a set of schemes is formed. For each scheme with the specific locations for SVC and TCSC installations, the MDCP is reduced to a continuous nonlinear optimization problem and the computing efficiency can be largely improved. Finally, to cope with the technical and economic concerns simultaneously, the scheme with the biggest utilization index value is recommended. The IEEE-14 bus system and a practical power system are used to validate the proposed method.
