A power system, under heavily loaded conditions, is at high risks of probable line outage and consequent voltage instability problem. Real power loss and voltage deviation minimization are reliable indicators of voltage security of power networks. This paper proposes a Particle Swarm Optimization (PSO) based optimal location and sizing of Static Var Compensator (SVC) to improve voltage stabilit...

A model has been developed to study the global complex dynamics of a series of blackouts in power transmission systems [1, 2]. This model has included a simple level of self-organization by incorporating the growth of power demand and the engineering response to system failures. Two types of blackouts have been identified with different dynamical properties. One type of blackout involves loss o...

This paper addresses the allocation of defensive or hardening resources in an electric power grid to mitigate the vulnerability against multiple contingencies. This planning problem is characterized by a defender-attacker-defender model which is formulated as a trilevel programming problem. In the upper level, the system planner identifies the components to be defended or hardened in order to r...

Since power transformer is a complex and critical component of the power transmission and distribution system, their reliability is crucially important for the energy system operation. So, there is an increasing interest in applying monitoring systems and on line diagnosis methods to transformers, as these are one of the most expensive and critical apparatus of a power system. Detecting failure...

Allowing better estimates of the risk associated with outages and asset failures is an ultimate goal since the cost of service interruption due to forced or planned outage can be substantial. This paper address how the risk calculation is improved by the use of Big Data related to weather and other environmental impacts that may lead to outages and asset deterioration. Big Data considered in th...

Prior work has shown the benefits of Energy Storage Devices (ESDs), such as batteries, to smoothen/flatten power draws in Datacenters, for reducing demand during peak tariffs (for op-ex savings) and under-provisioning the power infrastructure (for cap-ex savings). Until now, all prior studies for such smoothening, referred to as Demand Response, have considered re-purposing existing UPS unit ba...

According to the reports of power companies, about 80-90% of the outages occurred in the network are due to the error in the distribution system. The occurrence of these outages leads to the customer dissatisfaction and the lack of energy sales and significant economic losses in the distribution companies. Thus increasing network reliability to reduce these losses has attracted the attention of...
