Solar farm hourly dispatching using super-capacitor and battery system

This document researchs on 55kW GSHP black start based on 250kW/250kWh battery system and 50kW/10s super capacitor. The modeling methods of asynchronous motor, battery system, super capacitor and PCS are given. According to three black start conditions: direct start, star delta start and frequency conversion start, simulates and analyses the results. During black start, the max AC bus voltage drop reaches 60%, and hybrid energy storage system is able to effectively inhibit the inrush current.

Cellophane is a composite polymer material, made up of regenerated cellulose (usually derived from wood pulp) which has been chemically transformed into "viscose", then formed into a (1 mil thickness) transparent sheet through an extrusion process. Although primarily produced for the food industry, cellophane's use as a separator material in the silver-zinc secondary battery system has proved to be another important market. We examined 14 samples from five producers of cellophane, which are being evaluated as the separator material for a silver/zinc alkaline battery system in an autonomous underwater target vehicle. Our intent was to identify structural and/or chemical differences between samples which could be related to the functional differences seen in the lifetimes of these various battery separators. The unused cellophane samples were examined by transmission electron microscopy (TEM) and energy dispersive X-ray spectroscopy (EDS). Cellophane samples were cross sectioned (125-150 nm) using a diamond knife on a RMC MT-6000 ultramicrotome. Sections were examined in a Philips 430-T TEM at 200 kV. Analysis included morphological characterization, and EDS (for chemical composition). EDS was performed using an EDAX windowless detector.
