Suppression Strategy of Ultra-Low Frequency Oscillation in Yunnan Power Grid with BESS
2019 North American Power Symposium (NAPS), 2019Many problems related to power system frequency have occurred in Yunnan Province ─a province in southwestern China with high proportion of hydro-turbine generators. Yunnan Power Grid is a typical direct-current (DC) sending grid and the installed capacity of hydro-generators has accounted for more than 70% of the total capacity after asynchronous ...

Ultra Low Frequency Low Power CMOS Oscillators for MPPT and Switch Mode Power Supplies
2018 14th Conference on Ph.D. Research in Microelectronics and Electronics (PRIME), 2018This paper presents the design of two low power consumption analog oscillators implemented in a $0 . 35\mu \mathrm {m}$ CMOS technology. These oscillators were designed for a power conditioning circuit with an analogue Perturbation and Observation (P&O) Maximum Power Point Tracker (MPPT) to maximize the scavenged power generated by energy harvesting ...

Ultra Low Frequency Low Power Oscillator using Ultra-Capacitor and Advanced Flywheel
2018 International Conference on Smart Electric Drives and Power System (ICSEDPS), 2018Ultra-low-frequencies (< 1.0 Hz) are required for signal transmission in rocky layers for seismic studies. This frequency region is tougher to work on. Various methods of generating these frequencies have been in use since several years. In electrical science, it has been known ever-since that energy in electric field of a capacitor and energy in ...
