Control logic of smart microgrids in coal mines
FAN Hengchuan
Abstract：In response to the increasing proportion of new energy power in coal mine production,which is facing challenges such as low utilization rates due to the intermittency and volatility of new energy generation,as well as potential threats to the stability of coal mine power supply and distribution systems.A solution was proposed integrating a smart microgrid into coal mine power supply and distribution systems.By establishing the control system architecture,control models,and logical processes of a coal mine smart microgrid,and validating them through engineering case studies,the results demonstrate that the smart microgrid in the case project not only increased the new energy consumption ratio by 1.4%but also reduced the coal mine's annual electricity costs by approximately 16.3%through peak-valley electricity price arbitrage and optimized reserve capacity.
