Preventive Security-Constrained Optimal Power Flow Considering UPFC Control Modes
The successful application of the unified power flow controller (UPFC) provides a new control method for the secure and economic operation of power system. In order to make the full use of UPFC and improve the economic efficiency and static security of a power system, a preventive security-constrained power flow optimization method considering UPFC control modes is proposed in this paper. First...
متن کاملPower flow control with UPFC
The UPFC can provide simultaneous control of all basic power system parameters ( transmission voltage, impedance and phase angle). The controller can fulfill functions of reactive shunt compensation, series compensation and phase shifting meeting multiple control objectives. From a functional perspective, the objectives are met by applying a boosting transformer injected voltage and a exciting ...
متن کاملDE Based Optimal Power Flow for Location of UPFC Considering Voltage Stability
Optimal Power Flow (OPF) has been widely used in power system operation and planning. This paper presents Differential Evolution (DE) method to solve optimal power flow in power system incorporating a powerful and versatile Flexible AC Transmission Systems (FACTS) device such as Unified Power Flow Controller (UPFC). Unlike other FACTS devices, UPFC has a great flexibility that can control the a...
متن کاملComparison of Voltage Security Constrained Optimal Power Flow Techniques
This paper compares two different Optimal Power Flow (OPF) formulations that consider voltage security in power systems. The techniques are both based on multi-objective optimization methodologies, so that operating costs and losses can be minimized while maximizing the “distance” to voltage collapse. The techniques are described in detail and compared to study their similarities, as well as a...
متن کاملUmbrella Contingencies in Security-Constrained Optimal Power Flow
The notion of umbrella contingencies is rigorously defined in the context of the security-constrained optimal power flow (SCOPF) problem in both its deterministic and probabilistic forms. The set of umbrella contingencies is a subset of the set of credible contingencies that is sufficient to attain levels of security and economic performance identical or nearly identical to those found when all...
