“…Earlier works have used electric distance measures in a number of roles: [46] introduced nodeto-node voltage attenuation distances and used them in identifying voltage control zones; [47] used the same in assessing system voltage security; [48] to partition a system into localized reactive power markets; [49] used impedance sub-matrices to relate load and generator voltages as a distance metric for transmission use-of-system charging; later, and seemingly independently, Abdelkader et al [50][51][52] used closely related sub-matrices for power flow tracing and loss allocation purposes.…”

“…With this method, we can also determine which reactions can be eliminated from the system without losing full control. This type of analysis has been also used in the field of engineering to deal with matters on the control of electric circuit systems [41,[65][66][67][68]. In future, algorithmic improvements might result in a semiautomated method that can be used to reduce the complexity of entire networks.…”

The importance of systems-based pharmacological approaches to drug discovery and development has increasingly been recognized. This reviews summarizes recent advances in the development of systems pharmacology and introduces the methods used for analysis. To understand the cellular response at the molecular level, pathway maps must be prepared to show how the function of the constituent molecules within cells are linked and integrated to form molecular networks. First, the methods used to prepare these pathway maps, such as databases, knowledge bases and software platforms, are introduced. Then the mathematical theories used to analyse the behavior of molecular networks are summarized. To quantitatively predict cellular responses, simulations are performed that are based on the rate equations for each reaction within the pathway map. If the number of reactions described in the pathway map is small, and if the parameter values for the rate constants are available, it is possible accurately to simulate the behavior of the molecular networks. However, to analyse complex maps, mathematical abstraction is required. Such abstraction methods are important to integrate cellular responses and to understand tissue/organ and in vivo pharmacological/toxicological responses. The scope and limitations of the methods are also discussed.

-Recently, Korean system operating conditions have gradually approached an upper limit.When a contingency occurs, the power system may have no solutions. Different from the cases of bad initial guesses or the solutions are too close to the solvability boundary in which numerical methods can be applied, for unsolvable cases, the only way to restore solvability would be structure modifications. In this paper, a new approach for corrective and preventive control to such cases is proposed in two steps: (i) finding any solution regardless its feasibility; (ii) for the infeasible solution, make it feasible with additional modifications at load buses having Distributed Energy Resources. The test case built based on the peak load profile of 2008 by KEPCO including 1336 buses is analyzed. Since reactive power compensation is optimized to restore solvability, all demands are met, therefore no blackouts happen. The proposed method was integrated in the LP program designed by power21 Corporation.
