By changing the admittance of weak ties it is possible to increase or decrease the minimum singular values and thus to improve or deteriorate by the value of ∆δ kl . This value can be estimated 25 Coordinated Intelligent Operation and Emergency Control of Electric Power Systems the conditionality of the Jacobi matrix and the nodal admittance matrix. Contribution Factor of Power Transmission The contribution factor method (Bialek, 2000) makes it possible to determine for a known load flow between what ties in the electric network the power of each generator node is distributed and in what proportion.
State estimation for the 3-bus scheme (23-4). For the schemes with removed buses the problem of SE is not solved because of installation of the calculated PMUs there. Voltage magnitude and phase at bus 3 are calculated through SCADA measurements and the calculated PMU data. 6. Adjustment of power flows in the boundary branches 6-12; 6-11, 6-13, 4-3. The calculation results are shown in Table 4. 7. Analysis of the obtained results. Table 4 shows that condition (14) for the boundary branches is true (the difference between the calculated flow and the measurement is less than the threshold equal to 15 MW and 30 MVAr).
The system enhances control efficiency of normal and emergency conditions in the current market environment. Artificial Intelligence Methods in Problems of Operating Condition Monitoring Effective organization of the system of IPS operating condition monitoring is possible by an extensive involvement of new tools for the analysis and calculations of operating conditions, primarily technologies of artificial intelligence. It should be underlined that the methods of artificial intelligence have nothing to do with algorithmic calculations and therefore, do not require complex computational mathematical models to be constructed for an object.
