  • Design and Application of a Solar Mobile Pond Aquaculture Water Quality-Regulation Machine Based in Bream Pond Aquaculture.
    PloS one, 2016
    Co-Authors: Xingguo Liu, Yongjun Zhang, Changfeng Tian, Guofeng Cheng, Haisheng Zou, Shijing Liu, Tang Rong
    Abstract:

    Bream pond aquaculture plays a very important role in China's aquaculture industry and is the main source of aquatic products. To regulate and control pond water quality and sediment, a movable solar pond aquaculture water quality regulation machine (SMWM) was designed and used. This machine is solar-powered and moves on water, and its primary components are a solar power supply device, a sediment lifting device, a mechanism for walking on the water's surface and a control system. The solar power supply device provides power for the machine, and the water walking mechanism drives the machine's motion on the water. The sediment lifting device orbits the main section of the machine and affects a large area of the pond. Tests of the machine's mechanical properties revealed that the Minimum Illumination necessary for the SMWM to function is 13,000 Lx and that its stable speed on the water is 0.02-0.03 m/s. For an Illumination of 13,000-52,500 Lx, the sediment lifting device runs at 0.13-0.35 m/s, and its water delivery capacity is 110-208 m(3)/h. The sediment lifting device is able to fold away, and the angle of the suction chamber can be adjusted, making the machine work well in ponds at different water depths from 0.5 m to 2 m. The optimal distance from the sediment lifting device to the bottom of the pond is 10-15 cm. In addition, adjusting the length of the connecting rod and the direction of the traction rope allows the SMWM to work in a pond water area greater than 80%. The analysis of water quality in Wuchang bream (Parabramis pekinensis) and silver carp (Hypophthalmichthys molitrix) culture ponds using the SMWM resulted in decreased NH3(+)-N and available phosphorus concentrations and increased TP concentrations. The TN content and the amount of available phosphorus in the sediment were reduced. In addition, the fish production showed that the SMWM enhanced the yields of Wuchang bream and silver carp by more than 30% and 24%, respectively. These results indicate that the SMWM may be suitable for Wuchang bream pond aquaculture in China and that it can be used in pond aquaculture for regulating and controlling water quality.

  • ISGT - Lighting systems control for demand response
    2012 IEEE PES Innovative Smart Grid Technologies (ISGT), 2012
    Co-Authors: Sri Andari Husen, Ashish Pandharipande, Ludo Tolhuizen, Ying Wang, Meng Zhao
    Abstract:

    Lighting is a major part of energy consumption in buildings. Lighting systems will thus be one of the important component systems of a smart grid for dynamic load management services like demand response. We consider the problem of control of multiple lighting systems in a building for providing demand response service. In the scenario considered in this paper, under a demand response request, lighting systems in a building react by executing dimming control to reduce power consumption based on their load shedding flexibilities. Load shedding flexibility reflects the amount of power reduction that can be achieved by an individual controller without violating Minimum Illumination requirements of occupants in that area. We consider different methods for distributing load reduction across the multiple lighting system controllers employing their respective load shedding flexibilities. The performance of the methods is compared with a scheme where uniform dimming is applied across the lighting systems.

  • daylight integrated Illumination control of led systems based on enhanced presence sensing
    Energy and Buildings, 2011
    Co-Authors: Ashish Pandharipande, David Caicedo
    Abstract:

    Light emitting diodes (LEDs) are considered to become the dominant source of Illumination in the future, offering long life times, energy efficiency and flexible tunability. The flexibility of adapting LED parameters offers multiple degrees of freedom in designing LED based lighting systems. In this paper, we consider energy-efficient Illumination control design of LED based lighting systems in office spaces. Our goal is to determine the optimum dimming levels of the LED sources so as to minimize the power consumption while rendering (i) uniform Illumination at a given Illumination level in workspace regions that are occupied, and (ii) a Minimum Illumination level of lower value in unoccupied regions, while taking daylight distribution over the workspace plane into account. In order to determine occupant locations, we present an ultrasound array sensor solution with enhanced presence detection capability. We further propose a method to estimate and disaggregate Illumination contributions of daylight and the different LED sources at the workspace plane. The performance of our proposed control solution is evaluated under different occupancy scenarios.
