READ MORE1. What is a microgrid? A microgrid is a set of on-site energy loads and resources that work as a system and can operate independently of the grid. It can be as small as a few solar panels and a battery or as large as an array of solar, wind, hydrogen, and other systems across multiple facilities or a community.
READ MOREWith the increasingly prominent defects of traditional fossil energy, large-scale renewable energy access to power grids has become a trend. In this study, a microgrid operation optimization method, including power-to-gas equipment and a hybrid energy storage system, is proposed. Firstly, this study constructs a microgrid system
READ MOREThe identification of microgrid benefits is a multi‐objective and multi‐stakeholder interest coordination task. Due to the comparatively large number of different assumptions that could impact microgrid benefits, a basic standard test condition (STC) is defined to evaluate microgrid benefits under a "most likely to happen" scenario.
