Electric power systems foresee challenges in stability, especially at low inertia, due to the strong penetration of various renewable power sources.The value of energy storage system (ESS) to rubbermaid 8 gallon trash can provide fast frequency response has been more and more recognized.In this paper, we comprehensively evaluate the ESS candidates
The Effect of Lease Accounting on Credit Rating and Cost of Debt: Evidence from Firms in Korea
This study examines the effect of capital lease and operating lease options in accounting on credit ratings and the cost cga 200 to cga 510 adapter of debt using data for 13 years (2001 to 2013) on 6133 listed and unlisted domestic firms in Korea that recognize leases on financial statements.We use the Heckman two-stage model to control for sample
Comprehensive comparison of the delta- and wye-connected autotransformer applied to 12-pulse rectifier
12-pulse rectifier is extensively used in high power rectification, and the delta-connected autotransformer and wye-connected autotransformer are read more its two most popular phase-shift transformers.This paper compares the 12-pulse rectifiers using the two transformers via calculating the input line current, load voltage, kVA ratings of the two
Modified cosine-quadratic reflectance model
In the article, a new light reflectance model is proposed.The model is based on the modified cosine-quadratic bidirectional reflectance distribution function.The concept of bidirectional reflectance distribution function is analyzed.The disadvantages of existing physically accurate and empirical bidirectional reflectance read more distribution func
