En este artículo se presenta una propuesta de ensayo que permite la conformación de un banco de pruebas para caracterizar el panel PV mediante barridos de la curva corrientetensión (I-V) en función de la temperatura (T) e irradiancia (G) medidas. Para ello se utiliza un modelo circuital simple que permite modelizar una célula PV ideal y, a partir del mismo modelizar, asimismo, el panel PV a ensayar incluyendo las pérdidas óhmicas parametrizadas para una mejor caracterización de dicho sistema. Con los ensayos en diferentes condiciones de trabajo, y a partir de la utilización de un algoritmo de cálculo, se obtienen los parámetros del generador PV para la tensión en circuito abierto (V oc), corriente de corto-circuito (I sc), punto de máxima potencia (MPP: Maximum Power Point) y de la medida del rendimiento a partir del factor de forma (FF: Fill Factor). La metodología propuesta permite contrastar los datos del fabricante con los adquiridos bajo ensayo y con los obtenidos mediante simulación del panel PV mediante modelo circuital simple, permitiéndose una caracterización completa del panel fotovoltaico ensayado.

Ripple, voltage magnitude changes, and injected harmonics due to conversion switches are power quality issues for grid-integrated doubly fed induction generators (DFIG) wind sources. In this study, FACTS (flexible alternating current transmission system) devices like the static VAR compensator (SVC), thyristor controlled series compensator (TCSC), unified power flow controllers (UPFC), and static synchronous compensators (STATCOM) are used to stabilise wind energy with DFIGs. The simulation test cases using MATLAB also analyse three lines to ground fault (LLL-G) of fault measures, which showed a 9 MW that transferred to utility grid. Therefore, it is suggested to inject or absorb reactive power to stabilise the system using moth flame optimization with firebug swarm optimization (MFO-F...

Increasing renewable energy utilization, reliability and efficiency of system operation and flexibility of energy sharing amongst several microgrids (MGs) are some specific privileges of NMG. In this paper, residential MGs, commercial MGs, and industrial MGs are considered as a community of NMG. The loads’ profiles are split into multiple sections to evaluate the maximum load demand (MLD). Based on the optimal operation of each MG, the operating reserve (OR) of the MGs is calculated for each section. Then, the self-organizing map as a supervised and a k-means algorithm as an unsupervised learning clustering method is utilized to cluster the MGs and effective energy-sharing. The clustering is based on the maximum load demand of MGs and the operating reserve of dispatchable energy sources, and the goal is to provide a more efficient system with high reliability. Event...

Additionally, the optimum value of the aforementioned sizing ratio of a GCPV system is defined as the one that maximizes the yearly energy efficiency in the PV installation considered. The chapter defines Rs of a GCPV system with static configuration, and, starting from the respective PV generator (PVG) and central inverter models, it proposes a systematic procedure to determine its optimum value. This procedure will be adapted later to address the determination of the sizing ratio in reconfigurable GCPV systems. In fact, the chapter shows systems with adjustable Rs, differentiating between systems that adjust the sizing ratio value by modifying the rated power of the energy-processing subsystem used at each moment (the so-called MIX or Multi-master systems), and syst...

Due to this rise in the number of consumers of power systems and the unpredictable nature of the electric load, the vast power demand proves to be a tough challenge for electric utilities and system operators. So, power demands have occurred over many periods and become a threat to the system's functionality. Therefore, an effective Energy Management System (EMS) name called Golden Eagle Optimization with Incremental Conductance (GEO-INC) is proposed to meet the load demand. Three different systems, namely: RES Photovoltaic (PV) module, wind turbine, and battery create an effective EMS. The proposed method extracts more power from the PV panel and effectively controls the switching between the wind turbine and the battery storage system. The proposed method achieves 1.98 % distortion from the results, which is less than the existing methods.

An efficient energy management system can provide an adequate compromise in terms of the component sizing of NMGs through MG collaboration. This paper proposes a procedure to size the component for an isolated networked hybrid microgrid. The proposed design procedure relies on the optimum operation of individual MGs. The defined Reduced Factor (RF) identifies the possible size reduction for the dispatchable components, such as diesel generators and the energy storage system of each MG. The introduced RF is based on the operating reserve evaluation obtained from the optimal operation of individual MGs and the correlation between load profiles. Eventually, the simulation and practical results of a networked hybrid MG consisting of three MGs are presented to verify the proposed component sizing procedure. The pract...

This approach is based on a modification of the optimization strategy for adding absorption and flotation stages after each bulk charge to preserve the battery lifetime. These stages are computed out of the optimization program to reduce both computation complexity and convergence problems. Simulation results have confirmed the feasibility of this procedure at expenses of only a slight cost function increase, which can be assumed to preserve the battery lifetime.
