Careful design and planning is essential for successful integration of energy storage system (ESS) in a shipboard dc hybrid power system. An optimization model for resiliency enhancement and total cost reduction is proposed in this paper. The resilience of a shipboard power system with and without ESS are evaluated by means of resiliency index values under fault conditions. Furthermore, the influence...
Industrial power systems in the mining and metal industries typically comprise several large and fluctuating loads, such as crushers, excavators, shovels, and steel mills. Flexible distribution of energy and storage resources (FDERS) is a proposed new framework for reliably regulating the quickly varying loads supplied by a network of multiple smaller-rated distributed energy resources (DERs), especially...
In this paper, an economic evaluation is carried out for energy storage options in an industrial microgrid comprising four distributed energy resources (DERs). It is assumed that each DER unit is accompanied by Li-ion battery and/or supercapacitor for load following under islanded mode of operation. Cost estimates are made for different energy storage options based on present value of life cycle cost...
This paper evaluates the energy storage systems (ESS) in the microgrids. The ESS unit is regarded as an added energy resource in microgrid system to support the power balance when regular distributed energy resources (DERs) are incapable of matching the load demand. Sizing and specifications of ESS are investigated in this paper using several test case scenarios. An overall evaluation of the energy...
A new framework for integrating distributed energy resources (DERs) and energy storage devices, known as Flexible Distribution of EneRgy and Storage resources (FDERS), has been proposed recently. It offers the benefits of increased DER lifetime, optimal energy storage deployment, enhanced controllability and improved system robustness. This paper presents an autonomous cooperative agent based FDERS...
Flexible distribution of energy and storage resources (FDERS) offers the benefits of increased resource lifetime, optimal energy storage deployment, enhanced controllability and improved system robustness. It is enabled through the use of reconfiguration, variable interface reactances and/or adjustable distributed energy resource (DER) controls to create a cooperative framework among multiple interconnected...
