nowadays, congestion management is one of the major tasks accomplished by system operators to warrant the operation of transmission system within operating limits. this has resulted in unanticipated congestion interfaces in regional transmission systems. the system is, however, unable to evolve at a rate which is required to meet the quickly changing demand of competitive markets. to make the m...

the markowitz’s optimization problem is considered as a standard quadratic programming problem that has exact mathematical solutions. considering real world limits and conditions, the portfolio optimization problem is a mixed quadratic and integer programming problem for which efficient algorithms do not exist. therefore, the use of meta-heuristic methods such as neural networks and evolutionar...

For remote places having less-strong wind, single resources based renewable energy system (RES) with battery storage can sustainably and economically generate electrical energy. There is hardly any literature on optimal sizing of such RES for very low load demand situation. The objective of this study is to techno-economically optimize the system design of a Photovoltaic (PV)-battery storage RE...

this paper presents a new meta-heuristic solution to find the efficient frontier using the mean-variance approach. portfolio optimization problem is a quadratic programming model and, changes to np-hard if the number of assets and constraints has increased, and it cannot be solved using common mathematical methods in a reasonable time. therefore, a heuristic or meta-heuristic algorithm should b...

Diverse demands and dynamic environment of e-market makes market segmentation imperative for decision makers to devise strategies to woo varied groups. Market Segmentation is a process to segment the large and dynamic markets into separate sub markets where customers in the same group are similar with respect to a given set of characteristics. The most prevalent technique that is used for marke...

Economic Load Dispatch (ELD) problem in power systems has been solved by various optimization methods in the recent years, for efficient and reliable power production. This paper introduces a solution to ELD problem using a new metaheuristic nature-inspired algorithm called Firefly Algorithm (FFA). The proposed approach has been applied to various test systems. The results proved the efficiency...
