Journal ArticleDOI
Output power leveling of wind turbine Generator for all operating regions by pitch angle control
Tomonobu Senjyu,Ryosei Sakamoto,Naomitsu Urasaki,Toshihisa Funabashi,H. Fujita,Hideomi Sekine +5 more
TL;DR: In this paper, a generalized predictive control strategy based on average wind speed and standard deviation of wind speed was proposed to control the pitch angle of the blades of a wind turbine generator.
Journal ArticleDOI
Optimal Distribution Voltage Control and Coordination With Distributed Generation
TL;DR: In this paper, the optimal control of distribution voltage with coordination of distributed installations, such as the load ratio control transformer, step voltage regulator (SVR), shunt capacitor, shunt reactor, and static var compensator, is proposed.
Journal ArticleDOI
A Coordinated Control Method to Smooth Wind Power Fluctuations of a PMSG-Based WECS
Akie Uehara,Alok Pratap,Tomonori Goya,Tomonobu Senjyu,Atsushi Yona,Naomitsu Urasaki,Toshihisa Funabashi +6 more
TL;DR: In this paper, a simple coordinated control of DC-link voltage and pitch angle of a wind energy conversion system (WECS) with a permanent magnet synchronous generator (PMSG) is presented.
Journal ArticleDOI
Output levelling of renewable energy by electric double-layer capacitor applied for energy storage system
TL;DR: In this article, a current-source ECaSS (CS-ECS) is proposed, which consists of EDLC, bi-directional DC-DC converter, and current source inverter.
Journal ArticleDOI
A Novel Approach to Forecast Electricity Price for PJM Using Neural Network and Similar Days Method
TL;DR: In this article, a technique of artificial neural network (ANN) model based on similar days (SD) method was used to forecast day-ahead electricity price in the PJM market.
