“…the analysis checks whether the transition will lead to new equilibrium operating point. As a result of loss of dynamic stability, conditions such as loss of synchronism of some generators, transient voltage at a key bus falling below a certain level and operation of an out of step relay resulting in the opening of a heavy loaded tie line might be happen [23].…”

“…Under normal conditions, the system is operated so that it can withstand the loss of any one element [1] or one credible contingency. The ability of a system to withstand a list of "credible" disturbances or contingencies is defined to be operational reliability, but was previously called security [2]. This means that for any single contingency, the steady-state analysis converges to a solution that does not result in any limit violations in the post contingent system state.…”

Abstract-At the residential level, devices which are in place now and expected in the future have the ability to provide reactive power support. Inverters which connect distributed generation such as solar panels and pluggable hybrid electric vehicles (PHEVs) to the grid are an example. Such devices are not currently utilized by the power system. We investigate the integration of these end-user reactive-power-capable devices to provide voltage support to the grid via a secure communications infrastructure. We show how to determine effective locations in the transmission system and how to control reactive power resources at those locations. We also discuss how to determine reactive support groups which parallel the regions of the secure communications architecture that is presented. Ultimately, our goal is to present how the Smart Grid can allow the utilization of available end-user devices as a resource to mitigate power system problems such as voltage collapse.

Abstract.Increasing the intelligent level of the EPS control systems, caused by the implementation of Smart technologies, changes the structure and the properties of EPS and increases the importance of system reliability analysis. System reliability analysis includes two components -for the balance and for the regime. On the one hand, there is a large number of studies to assess the reliability of the power system, which examines various aspects and methods of solving this problem. On the other hand, in Russia there is no generally accepted methodology with clear criteria that could be used for feasibility studies of various technical solutions taking into consideration system reliability aspects. In practice, the security analysis is limited by the calculations of power flows, static and dynamic stability for a number of forecast periods for the normal and repair circuits considering the most severe disturbances. The existing approach allows defining the requirements and adjusting emergency control systems, but does not allow evaluating and comparing solutions for power grid constructions. The authors propose a new method for power system reliability evaluation, which is suitable for planning development and operation of power systems. The method includes a general description of the algorithm which allows to compare various development scenarios, as well as to assess the reliability level of their implementation. In particular, the method allows to determine where it is needed only the relay protection and emergency control system development, and where it is necessary grid, protection and control development and reconstruction.
