520 ▼a In existing AC PV systems, PV generates DC voltage, this DC voltage is inverted to AC through a grid-tied inverter and on the load side the AC voltage is converted to DC once again. This AC power system requires two energy conversion steps, DC/A
520 ▼a The aim of this work is to accelerate the deployment of DC systems by quantifying the benefits of DC systems compared to AC ,removing the technical barriers and addressing the issues related to safety and protection.
520 ▼a First, the two most popular architectures of DC microgrids are presented and the pros and cons of each configuration are discussed. Then, an emerging architecture for PV plus storage DC microgrids for commercial buildings is studied, which provi
520 ▼a Also, a comparative study between AC PV systems and a specific architecture of DC PV systems are presented. The study examines the DC system energy performance in different locations across the U.S. for several commercial building types and oper
520 ▼a DC microgrid control algorithm has to maintain stable power balance between generation and consumption. While ensuring power balance, the control algorithm should also control power sharing among sources and allow for multiple slack sources for
520 ▼a One of the purposes of this work is to quantitatively examine the stability and performance of the DC system. For the mentioned purpose, the model of the DC system including: all the components and their controllers are described in terms of mat
520 ▼a One of the limitations in using DC networks is the issues related to the current-limiting devices and circuit breakers. In this work, six configurations of DC circuit breakers from three categories are evaluated and the results are compared in t
