The normal distribution is a probability distribution in which the probability of a given value of the variable being observed is proportional to a power of the value. This paper deals with the simultaneous power system operation and system protection. We address the issues of system stability and the robustness of the protection schemes in the presence of a considerable system uncertainty. This paper deals with the stability of the system and the robustness of the protection schemes in the presence of a considerable system uncertainty. The results show that it is critical to study robustness of a protection scheme in a power system when the power system is coupled with other systems. This paper also examines the effect of random switching instabilities on the stability of the system. The approach to protect the system is to have a criterion for disconnecting switch that is based on a fuzzy logic of the power loss.

This paper provides a systematic review of power system disturbances, including power failures and noise and of the related protection schemes. The goal of this review is to assist those who have not dealt with this topic and provide a means to compare the current methods of protection. This review compares and contrasts the different tools used to deal with these disturbances and the protection schemes, including protection design parameters and outcomes, design rules, performance criteria, and evaluation methods. Although some of the methods for protection can be used in other areas of power system analysis and design, the emphasis in this review is on power system disturbances and protection. The review is organized as follows. The next section provides an introduction to power system disturbances. Section 3 reviews power system disturbances. A brief discussion of the different methods of analysis for protection design is provided in Section 4. Section 5 addresses protection design parameters. Section 6 reviews performance criteria. Section 7 discusses the different evaluation methods used to determine the performance of protection schemes. Finally, Section 8 provides a summary of this review.

Power system disturbances are disturbances to the steady-state operation of a power system and include a number of phenomena which can affect the operation of the system. Examples of these disturbances are power failures and noise, which may occur at any time and may have long and short durations. The problem of protecting a power system from disturbances has been of primary concern to engineers since the beginnings of electric power systems. Due to the complexity of the power system, there are no simple engineering answers to the problem of protecting the system. Rather, the engineering problem is to design a set of methods which, when applied in the correct sequence, are effective in protecting the system from large disturbances such as power failures or from smaller
