Efficient utilization of large-scale wind power is crucial to make the power industry economical and environment friendly. One way to consume wind power is through constructing isolated power systems with wind power supplying high energy consumption industries directly. However, one key issue, which limits the isolated power system for industry-wide application is to maintain the system frequency in an allowable range. To address this problem, a load-response control scheme for this kind of isolated power systems is presented and verified from the field tests in this paper. The testing results demonstrate that the electrolytic aluminum load reveals a good frequency regulation capability. Therefore, using frequency regulation capability from electrolytic aluminum provides an opportunity to fully utilize large-scale wind power in an isolated power system with high energy consumption loads.
