Optimization Algorithms for RES Operation Application With Utilization of Programmable Logic Controlers

The energy systems which consist RES will take a leading place in the energy world in future. From the one side the participation of RES (Renewable Energy Sources) and energy storage devices will increase the flexibility of the energy system and will offer new services at the energy market. From the other the probabilistic work of the RES lead to uncertainty in their production and may cause difficulties in the energy system operation. This two reasons together with the variety of RES and storage opportunities rise the necessity of building reliable algorithms for optimization of their work and their interoperability. Also concerning the future plans for energy systems development all energy systems including electricity, gas, heat, etc. should collaborate each other which increase the complexity of the algorithms for controlling the different systems. Usually, the optimization algorithm is part of MES (Manufacturing Execution Systems) or MOM (Manufacturing Operations Management) systems and they are executed in computers using different types of operation systems. In this article and approach for utilization of programmable logic controller as and algorithms holding devices is proposed. The utilization of the PLCs for such type of tasks will lead to improved performance of the algorithms and will increase the reliability and the speed of the algorithms. As the PLCs are relatively standard devices this will lead also to improved possibility for interoperability between different systems.
