- ENERGY MANAGEMENT ALGORITHM FOR END INSTALLATIONS WITH RENEWABLE PRODUCTION AND STORAGEPublication . Santos, Fernando; Hadla, HazemThis paper presents an algorithm to manage different renewable energy sourceswith storage. The objective of this algorithm is to regulate and control the outputcurrents of the DC-DC converters, which are directly connected to both the DC bus andthe inverter. Here, the inverter allows exchanging the energy between the DC bus andthe AC grid. The implementation of the proposed algorithm to end facilities in aliberalized market is also presented and tested. In addition, the benefits of suchimplementation, using eight dispatches, to the operators of the grid is demonstrated.The algorithm considers several situations of the consumption, energy production,various storage capacities, grid manager's demands, forecasts of production andconsumption loads. The results, which are obtained by the proposed algorithm, show agood regulation and control of the currents of the DC-DC converters, therefore a betterenergy management is achieved being this supported by an extensive theoretical analysis.
- Parameter Identification for Simplfied Set Current Predictive Control of SynRM DrivesPublication . Hadla, Hazem; Santos, FernandoIn this work, a simplified finite set current predictive control (FS-CPC) is presented for the synchronous reluctance motor (SynRM) drive due to its fast response and simplicity. However, the prediction model of this control is obtained from a mathematical model of the motor which contains many parameters, and thus any parametric uncertainly might lead to inaccuracies of the predictive algorithm. Therefore, the online identification of the stator resistance, and inductances of the motor are implemented using the recursive least square (RLS) technique. The identification method is built in Matlab/Simulink, and the obtained simulation results reveal its strong accuracy and effectiveness. Thus, the estimation technique is seen as a good option to be selected and combined with the simplified FS-CPC of the SynRM.
