IoTを用いたLPガスボンベ配送のピークカット効果

抄録

Low Power Wide Area network (LPWA) is widely spread, and support for IoT is progressing in Japan. In the current LP gas market, Sellers and distributors are possible not only to monitor their customers remotely but also obtain customers daily usage at low cost by LPWA. Applying daily metering through LPWA system makes distributors decrease their peak demand cost because they can visit their customers at a better timing. Then, in this paper, we discuss the peak-shaving for LP gas distribution by daily metering. At first, we formulate the integer programming problem (IP) for peak-shaving. The optimal solutions of IP show that applying IoT usage data decrease the peak load by almost 30 percent. At next, we analyze characteristics of the optimal solutions and propose the operational peak-shaving strategies every week. Applied our strategies to the actual data presents that they are well-functioning. Our strategies can easily install when LP gas distributors renovate their system corresponding to store IoT usage data.
