A CONSTANT-PRESSURE HYDRAULIC PTO SYSTEM FOR A WAVE ENERGY CONVERTER BASED ON A HYDRAULIC TRANSFORMER AND MULTI-CHAMBER CYLINDER

A Constant-Pressure Hydraulic PTO System for a Wave Energy Converter Based on a Hydraulic Transformer and Multi-Chamber Cylinder

This paper presents a constant-pressure hydraulic PTO system that can convert stored pressure energy into electrical energy at a stable speed through hydraulic motors and generators.A multi-chamber cylinder can be connected to the main power generation circuit by check valves, and the motor displacement can be controlled by a fuzzy controller to ma

State Estimation in Power Systems Under Random Data Attack Using Correlation Matching, Semidefinite Relaxation, and Truncated Eigenvalue Decomposition

This work considers a state estimation problem in modern power systems from the perspective of smart grids.Due to the use of digital technology, smart grids often encounter malicious data that is deliberately injected to attack their grid operations.Such kind of perturbation could be targeted at any domain of a smart grid from household customers t
