Design And Implementation Of Ccny Dc Microgrid Testbed, Mahmoud Saleh, Yusef Esa, Yassine Mhandi, Werner Brandauer, Ahmed Mohamed Oct 2016

Design And Implementation Of Ccny Dc Microgrid Testbed, Mahmoud Saleh, Yusef Esa, Yassine Mhandi, Werner Brandauer, Ahmed Mohamed

Publications and Research

This paper presents the design, control, energy management, and implementation of the City College of New York (CCNY) direct current (DC) microgrid laboratory testbed. This facility was custom designed and implemented by researchers at CCNY with minimal off-the-shelf components to enable significant flexibility and reconfiguration capability. The microgrid consists of renewable energy resources, energy storage system and controllable loads, and can operate in either a grid-connected or an islanded mode. The design steps, requirements, and results of the developed testbed were discussed. Moreover, several operational scenarios were tested. The experimental results verify the applicability and flexibility of the developed microgrid …


Impact Of Clustering Microgrids On Their Stability And Resilience During Blackouts, Mahmoud S. Saleh, Ammar Althaibani, Yusef Esa, Yassine Mhandi, Ahmed Mohamed Apr 2016

Impact Of Clustering Microgrids On Their Stability And Resilience During Blackouts, Mahmoud S. Saleh, Ammar Althaibani, Yusef Esa, Yassine Mhandi, Ahmed Mohamed

Publications and Research

In this paper, the impact of clustering multiple microgrids during blackouts, on their stability and supply availability, will be investigated. Microgrids have the capability of satisfying their emergency loads during blackouts. However, distributed energy resources (DERs)-dominated microgrids are affected by the uncertainty of their input energy supply, e.g. impact of solar irradiance on photovoltaic (PV) output. Moreover, an individual islanded microgrid is prone to instability issues due to large sudden load/generation changes. In order to increase the supply security, and enhance system stability, we propose to use the existing distribution grid infrastructure, if applicable, during blackouts to form microgrid clusters. …


Solar And Conservative Energy, Md Zahidur Rahman, Jonathan Anspike Mar 2015

Solar And Conservative Energy, Md Zahidur Rahman, Jonathan Anspike

Publications and Research

In the solar power and conservative energy, our basic mission was to build things that don’t use any sort of fuel that harms the environment. One of the most well-liked ways of conserving energy is using solar panels. Solar panels capture light, and transforms that light into electrical. The first objective in this research was to build an electric car that uses solar panels. To do so we connected a solar panel to a motor which rotates a series of gears that turns the wheels. We used a lot of sunlight though to power the motor enough were the gears …
