This study presents a control structure, based on model predictive control, applied to energy management optimisation in a sugar cane processing plant including renewable sources. The proposed energy plant is set upon a sugar cane processing industry and has to produce and maintain an amount of electric power throughout the year, defined by contract. This plant is, also, bound to produce flows of...
The paper aims to realize the micro-grid control in presence of distributed generation (DG) sources and the automatic voltage regulators (AVR). The provided analysis had into account highlighting the influence of the hybrid energy systems with consideration of the automatic voltage regulators on the power losses and the voltage level into micro-grids. The obtained results with the highest power/energy...
In this paper an off-grid hybrid energy system consisting of a reverse osmosis desalination plant for brackish water powered by renewable energy sources, and a diesel generator as back-up will be described. The whole system serves as a prototype for testing new automatic control methods to increase the plant reliability, which is crucial in remote arid areas. The necessary steps for the design of...
The Japanese government has set targets for increasing the contribution from renewable energy sources, such as wind power and photovoltaic (PV) generation. The fluctuating power of renewable energy sources, however, might degrade power quality such as voltage and frequency. To increase renewable energy near the demand side, a microgrid that utilizes controllable prime movers such as gas engines to...
