Multi-scenarios of effective demand side management in Navanakorn industrial promotion zone

Abstract

This paper studies the multi-scenarios of effective demand side management by implementing energy conservation programs in 51 designated factories according the Energy Conservation Promotion Act No. 2 B.E. 2550 (2007). In addition, 5% of peak demand reduction is estimated from the industries in Navanakorn industrial promotion zone that use to evaluate the effect of energy conservation programs and to investigate the limit of substation capacity. Moreover, the optimal management of diversity factor is indicated base on the estimated peak demand reduction by energy conservation programs and the annual demand growth of 3 substations. The surveyed results show that the peak demand can be reduced up to 1.97 MW with implementing energy conservation programs which mostly come from electronic ballast replacement measure. However, the analytical results of energy conservation project analysis show that the energy efficiency improvement is still a high potential for Navanakorn industrial promotion zone. Furthermore, the simulation results of multi-scenarios demand side management with the energy conservation programs illustrate that the substations can be supplied industries in Navanakorn industrial promotion zone until 2016 with 96.15% of total transformer capacity in case 5% of peak demand reduction from fully implemented energy conservation programs is achieved. Finally, the effective demand side management programs of the designated factories are the opportunity to extend the new substation
