The problem of voltage unbalance and its impacts on sensitive loads is well known. To solve these problems, custom power devices are used such as dynamic voltage restorer (DVR), which is most efficient and effective modern device. This paper discusses a review of the researches on the Dynamic voltage restorer (DVR) for power quality Improvement in power distribution networks. Sensitivity indust...

The electric utility industry is moving towards a deregulated, competitive environment where utilities must have accurate information about system performance to ensure that maintenance money are spent wisely and that customer expectation are met. To measure system performance, the electric utility industry has developed several performance measure of reliability. These reliability indices incl...

A model for blackouts in electric power transmission systems is implemented and studied in simple networks with a regular structure. The model describes load demand and network improvements evolving on a slow timescale as well as the fast dynamics of cascading overloads and outages. The model dynamics are demonstrated on the simple power system networks. The dynamics depend weakly on the networ...

Nowadays, the hybrid power system is getting popular because of its advantage of renewable integration to the traditional power grid. In this paper, a review of the hybrid power system is presented and detailed analysis of steady state & transient stability is performed. For detailed analysis, IEEE 9 bus system has been adopted and modified for this study. The proposed isolated hybrid system co...

The creation and delivery of power is one basic infrastructure expected by all modern industrial societies. Power distribution basics started in the US in the early 1900s when the first AC grid was established. Since 12 independent power grids were completed in the lower 48 states in the mid-1950s, reliability has been a customer concern. Parts of these earlier grids have been updated, and four...

A machine learning model is proposed in this paper to help estimate potential nodal load curtailment in response to an extreme event. This is performed through identifying which grid components will fail as a result of an extreme event, and consequently, which parts of the power system will encounter a supply interruption. The proposed model to predict component outages is based on a Support Ve...

In this paper, impacts of various uncertainties such as random outages of generating units and transmission lines, forecasting errors of load demand and wind power, in the presence of Demand response (DR) programs on power generation scheduling are studied. The problem is modelled in the form of a two-stage stochastic unit commitment (UC) which by solving it, the optimal solutions of UC as well...
