In the context of an increasingly competitive electricity 17 market, where prices are constantly rising and the presence of renewable energy resources is 18 gaining prominence, this paper analyzes the flexibility potential of customers in the meat industry, 19 based on the management of the most energy consuming process in this type of segment: cooling 20 production and distribution. 21The effectiveness of the proposed actions has been successfully tested and validated in an 22 active factory that produces cured ham in Spain, where savings of about 5% in the total annual cost 23 of electricity have been assessed, together with power reductions in the range of 50% of the total 24 * Corresponding Author: Manuel Alcázar-Ortega.

Electrical Market Management Considering Power System Constraints in Smart Distribution Grids

“…In addition, as most large industry consumers have supervisory control and data acquisition (SCADA) systems, the implementation of DSM in industry is much simpler than in traditional power systems. There are many works in this area, for instance, [45] assesses the potential of DSM in the meat industry. The customers in the commercial sector consume a large portion of the electricity and typically have a similar energy consumption pattern.…”

Integrated Power Management of Conventional Units and Industrial Loads in China’s Ancillary Services Scheduling

“…Jiang et al [15] designed a demand side frequency control scheme in an isolated wind power system, and evaluated the potential of aluminum smelting loads to participate in frequency regulation. Alcazar-Ortega et al [16] analyzed the flexibility potential of customers in one meat industry based on the management of the most energy consuming process in this type of segment: cooling production and distribution, which is one of the most representative sectors in Spain.…”

Evaluation and Assessment of New Demand Response Products based on the use of Flexibility in Industrial Processes: Application to the Food Industry

“…When the power load curve of a process has a flat shape, as shown in Figure 17, the following straightforward method can be applied, as proposed and validated in [4]. This method is based on the evaluation of the average power demanded when no flexibility actions are applied, and the subsequent extrapolation to time periods when the load shape is modified due to reductions and recovery periods.…”

“…However, after studying in detail the use of cooling in different factories located in Spain, where a wide range of different meat products are manufactured [4], four basic circuits for cooling production can be established for a typical meat production plant, as shown in Figure Figure 27. Scheme of processes in a typical cured meat products factory Four main cooling lines are present in a typical factory devoted to production of different meat products.…”

“…Nevertheless, it is worth highlighting that this is one of the industrial sectors which consumes the most electricity [4], with great potential for demand response implementation [5], [6].…”
