As the penetration level of photovoltaic (PV) generators into the grid is rapidly increasing, the effect of a variable PV power output on the stability of power systems cannot be ignored. Due to the stochastic characteristics of PV power generation, deterministic analysis approaches are not able to fully reveal the impact of high-level PV integration. This paper investigates the impact of the stochastic...
Accurate and reliable measurement of conveyor belt speed and vibration is of great importance in a variety of production and manufacturing industries. This paper presents the design, implementation and experimental assessment of an electrostatic sensor array for simultaneous measurement of conveyor belt speed and vibration in an on-line, continuous and non-contact manner. The sensor array is arranged...
In the production and manufacturing industries, speed measurement plays a significant part in condition monitoring and motion control of mechanical machinery. During operation, the friction between the sliding part and the air generates electrostatic charge that can be used for measurement of the linear speed. This paper deals with non-contact measurement of strip speed using electrostatic sensing...
This paper presents a simplified photovoltaic array model to describe the photovoltaic system features under partially shaded conditions. Based on the proposed model, the peak power sliding phenomenon of photovoltaic generation is studied during the above mentioned system dynamic process. The paper analyzes the mechanism of the peak power sliding and the critical sliding conditions. Simulation cases...
To assess the impact of intermittency of rapidly increasing solar photovoltaic (PV) generation on the grid, this paper presents the dynamic models of PV generation system, the battery energy storage system (BESS) and their associated control systems. The interfaces between these models and the mains grid are also provided. Using such dynamic models, the cloud transient impacts at different penetration...
This paper describes a newly-built broadband multiple input, multiple output (MIMO) channel characterization platform in indoor environment. The platform has been designed for measuring the S21 parameter between M transmitters and N receivers (M<;=8, N<;=8), which enables us to analyze the capacity and the directional multipath of the radio propagation channel. Data has been collected within...
