“…The set of measurements used by the MASE are generated from a power flow (PF) analysis of the modified IEEE 118-bus test system. In this case, the PF program permits the modeling of FACTS controllers, ALFC devices, and dependent loads, where only one reference node must be chosen to set the voltage angle profile in the solution [34]. After this study, a total set of 968 measurements is generated to perform the MASE study, where 146 synchronized phasor measurements are provided by 12 PMUs placed at control areas 2, 4, 6, and 7.…”

“…These estimations are compared with those values obtained by the power flow program used to generate the measurements [34] and with the estimations provided by a centralized SE implemented for this purpose based on the theory reported in Section 2; note that the same results were arrived at. Similarly, this validation is also met for the estimated values of the network state variables.…”

“…Some scholars take the static reactive power-voltage characteristics of generators and (or) loads into consideration [9][10][11] in their studies of steady-state operation analysis. The frequency regulation characteristics of generators are involved in models in Refs [12][13][14][15]. However, it needs to form the Jacobian matrix repeatedly in every iteration of the solution procedure, which will result in a large amount of calculation, and may not meet the requirement of online computation as the power system become larger and more complex.…”

Large-scale wind power (LSWP) integration may cause significant impact on power system frequency, so it is necessary to take frequency regulation issues into account in power system steady-state operation analysis. An improved fast decoupled power flow model considering static power-frequency characteristic of power systems with LSWP is proposed in this paper. In this scheme, the active power of generators and loads are presented with their static power-frequency characteristics. The slack bus degenerates to the nodal voltage phase angle reference bus of the system, and all the generators with frequency regulation capability participate in unbalanced power regulation. The power flow calculation results can reveal the impact to the system frequency of operation mode change and load variation, and present the output adjustment of the generators. The proposed model can be solved conveniently by the block solving technology based on the fast decoupled power flow algorithm. The scheme presented in this paper has been tested on the IEEE standard 30-bus test system by simulating basic operation and primary and secondary frequency regulation of the generators, which demonstrated the validity by the method.

Security risk assessment difficulties brought about by uncertainties can be solved by probabilistic power flow. A security risk assessment scheme of the power system using fast probabilistic power flow is proposed in this paper. The scheme applied probabilistic power flow on fast decoupled power flow model, considering multi-scenario of wind power and static characteristics of power systems, gaining the probabilistic distribution information of each desired variable by improved Von Mises method based on cumulants. Besides voltages and branch flows, the scheme can also obtain the distribution of frequency to assess the power system completely, which is not concerned in conventional probabilistic power flow calculation. The proposed algorithm was realized by programming based on Matpower 4.0. The examples executed on IEEE RTS-24 system demonstrate the rapidity, validity, and prospect for online application of the proposed scheme.
