How to design an effective and efficient load-frequency controller (LFC) for a multi-area interconnected power system to improve its power quality is a challenging issue. In order to deal with this issue, this paper presents a novel distributed fractional-order PID (DFOPID) control method for the load-frequency control of each area by using an adaptive population-based extremal optimization (APEO)...
Fractional order control theories have attracted increasing attentions recently due to their better control performance than traditional integer-order controllers, but there are few research works concerning their applications of power systems and power converters. This paper presents a novel binary-coded extremal optimization (BCEO) based fractional-order frequency control method for an islanded...
This paper is the first to present an efficient charge management algorithm focusing on extending the cycle life of battery elements in hybrid electrical energy storage (HEES) systems while simultaneously improving the overall cycle efficiency. In particular, it proposes to apply a crossover filter to the power source and load profiles. The goal of this filtering technique is to allow the battery...
Hybrid electrical energy storage (HEES) systems consist of multiple banks of heterogeneous electrical energy storage (EES) elements that are connected to each other through the Charge Transfer Interconnect. A HEES system is capable of providing an electrical energy storage means with very high performance by taking advantage of the strengths (while hiding the weaknesses) of individual EES elements...
Applications with Graphical User Interfaces (GUIs) are ubiquitous. Nontrivial GUI-based applications (GAPs) evolve frequently, and understanding how GUIs of different versions of GAPs differ is crucial for various tasks such as testing and project effort estimation. We offer a novel approach for comparing GUIs. We built a tool called GUI DifferEntiator (GUIDE) that allows users to visualize differences...
Peer to peer systems are distributed systems, decreasing system load is important for improving the scalability of systems. Caching is always used to achieve load balance in structured p2p systems currently, but none of the current caching algorithms take system load into consideration. We proposes a caching model for decreasing system load in structured peer to peer systems, describes how peer uses...
