Achieving supply demand balance in power systems requires controllable energy storage. The primary sources of controllable storage are the fuel stockpiles at generators (i.e. gas, coal, water, etc.). There is increasing interest in alternative forms of storage due to factors such as the continuing increase in intermittent energy generation sources, concerns with increasing network costs and demand...
Quality of Service (QOS) is a measure of the ability of the power system to reliably provide loads electrical power with the power continuity required by the loads. QOS recognizes that different loads can tolerate different power interruption durations. This paper reviews QOS concepts as described in IEEE 1662-2008 and IEEE 1709-2010, describes methods for employing QOS in the design of shipboard...
Various energy storage systems have been adopted in power systems for economic and reliability reasons. In order to maintain the reliability of power systems, reserve power needs to be scheduled against possible generation unit outages. The variation of wind power outputs also requires additional reserve power in addition to the reserve for the possible generation unit outages. Superconducting Magnetic...
This paper presents a optimal control and allocation strategy for Internal combustion-Linear Generator integrated Power System (ICLGIPS), the main objective of the strategy is to improve efficiency of the system. Linear generator (LEG) works alternately as electromotor and generator during one work period, energy storage device converts and transfers energy between power source and LEG, energy conversion...
Wind power has been considered as an environmental friendly electrical generation resource; however, the high wind power penetration can lead to high-risk levels in power system reliability. Energy storage system (ESS) is a promising means to smooth variations of wind power and improve the system reliability. Simulation models for assessing generation adequacies of power systems with wind power generation...
