اقرأ أكثرEnergy Management (EM) should first ensure that the load is met, thereafter to maximize efficiency and minimize operation-cost ( Yu et al., 2019 ). The EMS of MGs in the literature consider single MGs, in islanded and grid-tied modes in addition to multi-microgrids (MMGs) in which EM is considered for a MG community.

اقرأ أكثرThe study also shows that the recirculating load is higher with the VSI than with the cone crusher. Compared to the cone crusher, the VSI product contained 65% more material smaller than 1 mm while at the same time consuming less power. An alternative energy measure was introduced to assess the value of feeding a finer product to a grinding mill.
