4. Combining power limiting, interruption and peak load shifting together and striving for unit tripping without line tripping. To the industrial enterprises, according to the load change condition, the regulation of three days for power interruption and four days for power supply in a week was carried out and power limiting, interruption and peak load shifting were combined together. Aiming at the actual condition that the difference between peak load and valley load during day and night was high and load factor was low in the district center, from June 21, the regulation of three days for power interruption and four days for power supply in a week was applied to the production time of general enterprises, which was adjusted from 21:30 in the evening to 8:00 next day; it was not allowed to arrange production in the other time. Some continuous operating enterprises whose product quality was greatly influenced by power interruption and raw material waste was comparatively higher or enterprises which have heat preservation requirements could carry out production according to the capacity and time period approved by the chief administrative department. However, with the aggravation of high temperature and the increase of load shortage, the emergency load for part of continuous operating enterprises was stopped and the production was stopped completely in the daytime so as to give the power consumption priority to the residents. To large marketplaces, hotels, and buildings, when power consumption peak appeared, in the absolutely necessary condition, it was allowed to inform building and hotel users and others to require them to stop using air conditioning equipment for 0.5–1 h temporality to avoid passive situation of power interruption of all lines through peak load shifting.
