Voltage control scheme to enhance the stability for current distribution networks connecting with distributed generation (DG). The increasing demand of energy in recent years transformed traditional grids, which have unidirectional power flow Active Distribution Networks (ADN), including significant penetration renewable generators (DGs), such as photovoltaic (PV) modules where became bidirecti...

Power quality is considered as one of the most important issue in power distribution systems. Voltage sag is considered as one of the most common power quality problems. It may cause sensitive equipment to malfunction and process interruption. In this work a method of optimal network reconfiguration is proposed to mitigate voltage sag problem in power distribution networks. It is applied to a d...

As an internal parameter of ball milling process, grinding concentration (GC) is not able to be measured directly. According to ball mill’s principle, based on radial base function (RBF) network, a soft sensor method is presented to estimate the ball mill’s GC. And a novel grey relation analysis method as a way to determine the secondary variables is proposed. Simulation results demonstrate tha...

This paper designs a reliability distribution network with limited capacity under partial and complete facility disruptions. To increase the reliability of the distribution network, a new mixed integer linear programing model is developed by considering multiple mitigation strategies including diversification, fortification, and transshipment. The distribution network constitutes of reliable di...

The impending deregulated environment facing the electric utilities in the twenty first century is both a challenge and an opportunity for a variety of technologies and operating scenarios. Changing regulatory and economic scenarios, energy savings and environmental impacts are providing impetus to the development of an Active Distribution Networks (ADN), which is predicated to play an increasi...

Forecasting exchange rates is an important financial problem that is receiving increasing attention especially because of its difficulty and practical applications. This paper proposes a Hierarchical Radial Basis Function Network (HiRBF) model for forecasting three major international currency exchange rates. Based on the pre-defined instruction sets, HRBF model can be created and evolved. The ...

With more and more distributed photovoltaic (PV) plants access to the distribution system, whose structure is changing and becoming an active network. The traditional methods of voltage regulation may hardly adapt to this new situation. To address this problem, this paper presents a coordinated control method of distributed energy storage systems (DESSs) for voltage regulation in a distribution...
