Optimal Use of Hybrid Renewable Energy System for Educational Building

The paper demonstrates the influence of leading variables on the quality evaluation of the operation of univariate control loops of a multi-loop control system used in a 1000 MW power unit. We analyse the course of the setpoint and process values, the calculated value of the control signal and the disturbances values and leading variables. The variables that determine the operating point of the object are used as leading variables. In the case of a power unit, the main leading variable is the power setpoint at which the unit operates. The power setpoint determines the flow of fuel, air and steam—the values of these variables were also considered in the control qualityassessment. Methods based on the characteristics of control signals and error values (residual) are used in the loop control quality assessment. Basic metrics, such as mean error, mean absolute error and mean squared error, are used to analyse the control error. In addition, statistical measures in the form of higher degree moments are applied using the difference in their estimations. The study indicates that once the leading signal values are taken into account during the assessment, the risk of incorrectly interpreting decreased values for the considered indicators is minimized. It is shown that it is important to consider the values of leading variables because they determine the operating point. Particular attention is paid to changes in the leading values since they affect the process conditions. This paper discusses mechanisms that could allow control quality to be monitored both under stable operating conditions and during operating point changes. It is shown that even relatively simple metrics can give very good results when leading signals are considered.

“…Likewise, the use of conventional energy sources has increased over the years as the demand for energy has increased to better meet society's standard of living [3]. The growing need for energy has led to an increase in the use of energy from renewable energy sources [4] [5]. In addition, it is certain that hybrid power will play a key role in future electricity generation due to the rapid depletion of conventional power [5] [6].…”

This research is a systematic review of the irrigation system with hybrid energy compared to conventional energy, between 2015 and 2022. The main objective is to evaluate the effects of the irrigation system activated with hybrid photovoltaic -wind energy compared to conventional energy for water supply in agricultural areas, explained on energy saving, CO2 reduction, and irrigation of agricultural areas. The methodology used is based on the Prisma 2020 Declaration, Scopus, Google Scholar, and Redalyc databases were used, finding 20 articles; the results demonstrate the importance of the use of new emerging technologies such as IoT, Artificial Intelligence, among others, optimizing the proper use of water resources in irrigation for agricultural areas, however, renewable energies, such as hybrids, must be incorporated; which applies in countries such as

The output power delivered by a photovoltaic (PV) module to charge a battery is dependent on solar radiation incident upon it and the ambient temperature. To reduce PV energy loss, the PV panel is kept at peak efficiency by operating the PV system at the maximum power point (MPP) to deliver maximum power to the battery under charge. In this work, Perturb & Observe (P&O) algorithm was implemented in conjunction with constant voltage (CV), using the MATLAB/Simulink tool. Results obtained from these simulations show that the tracking efficiency of the P&O algorithm decreases with solar irradiation. However, the relatively good performance of the CV algorithm at low irradiation levels augments the P&O method. Both algorithms were implemented in a maximum power point tracking (MPPT) design using an ATMega328 microcontroller operating on a minimal Arduino-compatible integrated development environment (IDE) prototype circuit.
