The Economic Load Dispatch (ELD) problems in power generation systems are to reduce the fuel cost by reducing the total cost for the generation of electric power. This paper presents an efficient Modified Firefly Algorithm (MFA), for solving ELD Problem. The main objective of the problems is to minimize the total fuel cost of the generating units having quadratic cost functions subjected to lim...

Known and unknown behaviors of three nonlinear systems are described in this paper. The power harvesting project is mentioned where the power generation mat using piezoelectric elements was experimented and demonstrated in Tokyo station of Japan Railways east (JR-east) company in 2006 and 2008 respectively. The commuters and passengers generate electric power by passing the power generation mat...

Introduction of new technologies such as energy storage systems, electric vehicles, and distributed generation improved the characteristics of networks. On other hand, using these components in distribution systems improves system performances such as power losses. One of effective methods for improving system characteristics is distribution network reconfiguration. In this study, in addition t...

Due to the deregulation trend in electric power system networks, many factors have to be taken into consideration such as lack of supplying electric power, system reliability, power quality, electric system losses and voltage disturbance and profile problems. The excessive growing needs for electricity force electrical researchers to implement new approaches through the electric system. Introdu...

When large capacity distributed generation including photovoltaic (PV) systems are installed in power systems, reverse power flow from PV systems may cause problem of surplus electric power. To reduce the reverse power flow without the reduction of PV power generation, energy management of customer equipment such as electric water heater is one of the solutions. Therefore, cooperative control o...

Wind generation with an uncertain nature poses many challenges in grid integration and secure operation of power system. One of these operation problems is the unit commitment. Demand Response (DR) can be defined as the changes in electric usage by end-use customers from their normal consumption patterns in response to the changes in the price of electricity over time. Further, DR can be also d...
