Supervisory control design for systems of multiple sources of energy

A Novel Implementation for efficient PLC based low-power photovoltaic generation plants

“…However, several additional functions are also required by autonomous systems, ensuring economic management of the electric power whilst reducing the cost of maintenance [4]. On such an effective and universal device is the programmable logic controller, which can perform a range of tasks, formulated as algorithms [5][6][7]. Here are some of the functions not normally covered by common MPPT controllers: 1 Automatic selection of power source based on a pre-set priority order, giving preference to the lowest unit price for energy (kWh).…”

Model Predictive Control and Generalized Adaptative PID for Load Sharing In Systems of Multiple Sources of Energy

“…Furthermore, several works on hierarchical control have suggested the coupling and decoupling of sources [1], [8], [9]. In this paper, a control scheme is proposed based on a hierarchical approach previously developed by the authors [9]. Indeed, in their previous works [10] the authors have shown that the duty cycle value (DC/DC converter input control) is a variable that correlates negatively the available energy and the energy required by the load.…”

“…Usual controllers include fuzzy logic [12], [10], neural network [13], [14], predictive control [15], [16] and multi objective optimization [1]. Furthermore, several works on hierarchical control have suggested the coupling and decoupling of sources [1], [8], [9]. In this paper, a control scheme is proposed based on a hierarchical approach previously developed by the authors [9].…”

“…In the first approach, the main purpose is to reduce the initial investment capital [5], [6]. In the second approach, various strategies are proposed especially for local optimization, coordination of sources and control of the load [1] [7], [8], [9], [10]. The optimization by accepting a load shedding is also studied [11] as well as the availability on the market of equipment [8] In some cases a shedding not larger than 5% may impact strongly on the cost (Bilal and al.…”

Energy-efficient control of a multi-section supercapacitor power supply of an electric drive

“…In the publication [3], the authors consider the possibility of increasing the energy efficiency of actuators based on the use of the load torque predictor in the drive control law. The paper [4] describes a supervisory energy efficiency control strategy for electrical energy transfers in multisource renewable energy systems. In the paper [5] an efficient energy-management system for a hybrid electric vehicle, using ultracapacitors and neural networks, was developed.…”
