This paper is a summary of the development and demonstration of an optimization program, voltage VAR optimization (VVO), in the Korean Smart Distribution Management System (KSDMS). KSDMS was developed to address the lack of receptivity of distributed generators (DGs), standardization and...

As wind power penetration grows, the amount of reserve needed on the system also grows, due to the increases in the uncertainty of wind power, which grows larger as forecast horizon increases. By scheduling the system more often the amount of extra reserve to be carried to cater for wind...

Electricity markets are currently evolving to accommodate large scale penetration of wind generation. In this research, potential changes to the classification and role of windgenerators in the Single Electricity Market (SEM), the market for Northern Ireland and the Republic of Ireland, are...

In the analysis of time series of blackouts a powerlaw dependency of blackout size with respect to frequency hasbeen observed. It has been hypothesized that this behaviour is theresult of the power system operating near critical points. Modelshave been created in order to analyze this type of...

This paper presents a new fundamental approach to modal participation analysis of linear time-invariant systems, leading to new insights and new formulas for modal participation factors. Modal participation factors were introduced over a quarter century ago as a way of measuring the relative...

This paper presents a multi-objective mathematical model to perform power restoration. It considers simultaneously the objective functions: restoration time, load shedding, and cost. New formulations are developed to improve the maneuverability of the system elements. This distinguishes the...
