Hybrid energy storage system (HESS) composed of lithium-ion battery and supercapacitors has been recognized as one of the most promising solutions to face against the high cost, low power density and short cycle life of the battery-only energy storage system, which is the major headache hindering the further penetration of electric vehicles. In this work, the HESS sizing and energy management p...

The purpose of the Energy Management System (EMS) is to ensure a high degree efficiency, stability, and dependability. And electrical system should have ability adjust majority changes such as renewable energy integration. In some situations, power generated by distributed sources greater than local demand. This has an effect on microgrid's stability frequency. Smart management in microgrid pro...

The effective and sustainable environmental performance of a business is a result of various factors and most important the integrated outcome of the environmental management. Likewise, the integration of environmental protection into the armed forces functions has also gain interest for the military sector internationally. Therefore, the environmental management system (EMS) is recognized as o...

Abstract The outcome of this paper is to suggest an efficient energy-management strategy (EMS) for a direct-current (DC) microgrid (MG). typical MG composed two renewable energy sources [photovoltaic (PV) systems and fuel cells (FCs)] energy-storage elements (lithium-ion battery supercapacitor). An EMS was proposed ensure optimal bus voltage with power-sharing arrangement between the load sourc...

The paper broadens the scope of environmental management system (EMS) research by describing how EMSs can contribute to inertia in present production systems. In conjunction with other factors this inertia can inhibit dramatic shifts toward more sustainable technologies and systems. Our approach builds upon technological lockin theory, which focuses on market coordination and technological inte...

Renewable Energy Source (RES) based Distributed Generation (DG) like Photovoltaic (PV) is widely integrated into the distribution network, particularly for residential. With proper planning, installation of optimal PV in network capable minimizing dependency on power grid generation. However, optimum use solar energy has been limited by weather and load variation. At particular time, generated ...

This paper presents an energy management system (EMS) based on a novel approach using model predictive control (MPC) for the optimized operation of power sources in hybrid charging station electric vehicles (EVs). The is composed photovoltaic (PV) system, battery, complete hydrogen fuel cell (FC), electrolyzer (EZ), and tank as storage (ESS), grid connection, six fast units, all which are conne...

INTRODUCTION The concept of emergency medical services (EMS) is new to Sri Lanka. This article describes the development, delivery, and future ideas for EMS in Sri Lanka. Sri Lanka also faces frequent natural hazards that justify the establishment of an EMS service. METHODOLOGY Data and information regarding emergency medical care in Sri Lanka were collected and reviewed from resources includ...
