“…4 The authors conclude that the Fast Speed Control strategy is detrimental to grid stability. This is illustrated by the simulation of an event calling for a reduction in power (in this case, a step reduction in the active power set point).…”

“…The rotor current follows these commands with negligible delay. As currents of the rotor and stator are closely related, the current injected by the DFIM into the grid [3][4][5] may be determined also based on the commands issued by these controls. This fundamental consideration allows us to dramatically change the approach to modeling of the DFIM controlled by a power converter connected to its rotor winding.…”

This page intentionally left blank. PrefaceThis report is one of several reports developed during the U.S. Department of Energy (DOE) study on the Modeling and Analysis of Value of Advanced Pumped Storage Hydropower in the United States. The study is led by Argonne National Laboratory in collaboration with Siemens PTI, Energy Exemplar, MWH Americas, and the National Renewable Energy Laboratory. Funding for the study was provided by DOE's Office of Energy Efficiency and Renewable Energy (EERE) through a program managed by the EERE's Wind and Water Power Technologies Office (WWPTO).The scope of work for the study has two main components: (1) development of vendorneutral dynamic simulation models for advanced pumped storage hydro (PSH) technologies, and (2) production cost and revenue analyses to assess the value of PSH in the power system. Throughout the study, the project team was supported and guided by an Advisory Working Group (AWG) consisting of more than 30 experts from a diverse group of organizations, including the hydropower industry and equipment manufacturers, electric power utilities and regional electricity market operators, hydro engineering and consulting companies, national laboratories, universities and research institutions, hydropower industry associations, and government and regulatory agencies.The development of vendor-neutral models was carried out by the Advanced Technology Modeling Task Force Group (TFG) led by experts from Siemens PTI with the participation of experts from other project team members. First, the Advanced Technology Modeling TFG reviewed and prepared a summary of the existing dynamic models of hydro and PSH plants that are currently in use in the United States. This is published in the report Review of Existing Hydroelectric Turbine-Governor Simulation Models. The review served to determine the need for improvements of existing models and for the development of new ones.While it was found that existing dynamic models for conventional hydro and PSH plants allow for accurate representation and modeling of these technologies, it was concluded that there is a need for the development of dynamic models for two PSH technologies for which at present there are no existing models available in the United States. Those two technologies are (1) adjustable speed PSH plants employing doubly-fed induction machines (DFIMs) and (2)

“…Currently, the thyristor based cycloconverter is the most widely-used converter topology of doubly-fed adjustable-speed pumped storage plants, due to the development of the power electronic devices, control strategy, etc. [3][4][5]. The cycloconverter-based adjustable speed pumped-storage hydropower plants consist of a three-phase breaker, doubly-fed induction machine (DFIM), stator and rotor transformers, and cycloconverter.…”

Frequency-Adaptive Modified Comb-Filter-Based Phase-Locked Loop for a Doubly-Fed Adjustable-Speed Pumped-Storage Hydropower Plant under Distorted Grid Conditions

Abstract:The control system of a doubly-fed adjustable-speed pumped-storage hydropower plant needs phase-locked loops (PLLs) to obtain the phase angle of grid voltage. The main drawback of a comb-filter-based phase-locked loop (CF-PLL) is the slow dynamic response. This paper presents a modified comb-filter-based phase-locked loop (MCF-PLL) by improving the pole-zero pattern of the comb filter, and gives the parameters' setting method of the controller, based on the discrete model of MCF-PLL. In order to improve the disturbance resistibility of MCF-PLL when the power grid's frequency changes, this paper proposes a frequency-adaptive modified, comb-filter-based, phase-locked loop (FAMCF-PLL) and its digital implementation scheme. Experimental results show that FAMCF-PLL has good steady-state and dynamic performance under distorted grid conditions. Furthermore, FAMCF-PLL can determine the phase angle of the grid voltage, which is locked when it is applied to a doubly-fed adjustable-speed pumped-storage hydropower experimental platform.
