“…In [8], the benefits of using a centralized compressed air production as shown in Figure (3), instead of the decentralized solution of Figure (2) are reported. Using a multilevel pressure compressor, instead of n independent smaller compressors, it is possible to provide air to different networks, by properly operated valves.…”

A compressed air system feeds several end-users, each of them requiring air at a proper pressure; from an energy saving point of view, the network should work at the lowest functional pressure that meets production requirements. When different working pressures occur in the same plant, a rank of the final end-user, based on their operating pressure, is necessary; for each of the identified end-user macro-group, a decentralized set of compressors could be designed, thus involving higher installation and maintenance costs.This paper introduces to a new configuration in the compressed air production, when several operative pressures exist. The new network layout deals with a single compressor, fixed speed-electrically driven, and a centralized type of production, alternative to and more efficient of a decentralized one. A closed loop control method for a radial multilevel pressure air network is presented. Using a multilevel pressure compressor, instead of n independent smaller compressors, it is possible to provide air to different networks, by properly operated valves on the compressor. A set of suitably controlled valves intercepts air at the desired pressure level and feeds the networks while their operation guarantees that each pressure level is kept inside safe ranges. The centralized compressed air production is made possible by inheriting the real time scheduling theory: the idea is to state how to design a valves opening and closing sequence, delivering the required air amount to end-users, guaranteeing, at the same time, a proper pressure level inside each of the systems. In this way, higher efficiencies of bigger machines can be better exploited for the sake of energy saving.A theoretical case study with three different networks, operating in the range of 0.75, 1.0 and 1.3 M P ag is proposed. The following proposal integrates a previous work, besides, future developments are also anticipated.

“…In this sense, the proposed approach represents a general framework for the management of power/energy systems made by a huge number of components. Beside the industrial process described in this paper, other examples of heterogeneous systems that can be modeled using the proposed approach are Heating Ventilating and Air Conditioning systems (HVACs) [6] and air compressed systems [8]. Such systems are rather common in industries, buildings and apartments.…”

“…A statistical assessment of real-time scheduling techniques applied to power systems is provided in [7] by comparing with absence of explicit load control. In [8] real-time techniques are used to model and schedule the opening of valves in air compressed systems to reduce the total energy required for air compression. A similar approach is discussed in [9], where the "green scheduling" problem is defined as the peak load reduction problem faced by load scheduling.…”

A new approach based on real-time scheduling has been recently proposed for the management of electric loads composing a power system with the goal to reduce the peak load of power consumption. The novel idea is to model the power system in terms of timing parameters traditionally adopted in the field of real-time computing systems. In this way, the activation/deactivation of devices can be managed using classical scheduling algorithms developed for executing processing tasks in real-time systems. To prove the effectiveness of the proposed methodology, this paper shows its application to an industrial plant. Electric loads are modeled using timing parameters and a real-time scheduler is used to coordinate their activation. The coordinated management achieves the peak load reduction while meeting given constraints on the industrial process under control. The paper presents the modeling approach of the industrial process. The behavior of the control method is assessed by a simulated example.
