Title:

Designing a Distributed Energy Resource Model of the UNH Microgrid

In today's world the push to use more clean energy in the power grid is higher than ever before. This is important for reducing the effect nonrenewable forms of energy have on our climate and environment, as well as the ability to meet the ever-increasing demand of electricity in our society. However, renewable Energy Sources such as wind or solar, are often intermittent since their efficiency depends on outside stimuli such as wind speed or the amount of sunlight present. Understanding the role and affect renewable energy resources have on existing grid infrastructure and their intermittent behavior is an important thing to know for engineers looking to improve and maintain the grid. This Project was designed to model the base case of the Oyster River Clean Innovation project which improves the UNH-Microgrid by adding 3MW of Solar Power, and a 2MW/8MWh Battery Energy Storage System to the existing grid infrastructure, using the Simscape Power systems toolbox in MATLAB Simulink. All forms Distributed Energy Resources were successfully modeled in MATLAB as individual systems, including the Photovoltaic arrays and the 3 existing turbine generators. However, the model struggled when these resources were connected to a model of the Grid load structure, also produced in Simulink.
