“…Nevertheless, there are investigations where the mathematical part that represents the behavior of the centrifugal pump in the form of designed software combines with the hardware part, which imitates hydraulic loads according to the control program [27].…”

The purpose of the study is to analyze the prospects for the development of loading methods for gas turbines as well as to develop a mathematical model that adequately describes the real operating conditions of the loading system at various loads and rotation speeds. A comparative analysis of the most common methods and technical means of loading the shafts of a free turbine at gas turbine plants intended for operation as part of gas pumping units is presented. Based on the results of the analysis, the expediency of using the loading model “Free Power Turbine Rotor–Hydraulic Brake” as a load simulation is shown. Recommendations for the creation of an automation system for the load testing of power plants have been developed. Mathematical models and Hardware-in-the-Loop simulation models of power plants have been developed and tested. One of the most important factors that predetermine the effectiveness of the loading principle is the possibility of software implementation of the loading means using software control systems that provide the specified loading parameters of the gas turbine.

“…Different techniques are used to control the input speed of the pump. For example, in (Ghafouri and Khayatzadeh, 2012;Xu et al, 2016) a PID controller is designed and evaluated in simulation, while in (Gevorkov et al, 2016) a Hardware-in-the-Loop simulator is carried out, where the variable speed driver is connected via a programmable logical controller. In (Coccia et al, 2019), a water loop heat pump of a supermarket is used in a DSM strategy to minimize the yearly energy cost, by shifting the electricity demand; whereas, in (Arteconi and Polonara, 2018), the heat pump flexibility of a building is used in off-peak hours by DR programs.…”

Las redes eléctricas inteligentes están integrando fuentes de generación renovable, lo cual puede producir desbalances en la red eléctrica debido a variaciones en la radiación solar. Se proponen programas de Respuesta de la Demanda (RD) para reducir los desbalances. La gestión de cargas flexibles mediante agregadores se propone para proveer servicios complementarios en RD. En esta tesis, se propone un marco para agregadores desarrollando modelos de cargas flexibles y estructuras de control directo de carga capaces de proveer servicios complementarios. El marco considera una metodología para que las cargas presenten servicios y se evalúa en Sistemas de Elevación de Presión de Agua (SEPA), unidades de Refrigeración TermoEléctrica (RTE), y cargadores de Vehículos Eléctricos (VE). Primero, se estima un modelo dinámico del SEPA y se sintoniza con datos experimentales. Se propone un agregador de SEPA para ofrecer servicios de reserva rodante. Segundo, se estima un modelo dinámico de la RTE y se caracteriza con datos experimentales. Se propone un agregador de RTE capaz de ofrecer reserva de contención de frecuencia. Tercero, se desarrolla un modelo dinámico de un cargador de VE, y se propone un agregador de cargadores de VE que busca minimizar el costo mientras maximiza la flexibilidad. El agregador puede ofrecer servicios de reserva rodante, y participar en mercados del día siguiente y de tiempo real. Se formula una definición de flexibilidad para cargadores de VE. Los resultados muestran la validación de los agregadores por medio de simulaciones, cumpliendo los tiempos y capacidades solicitadas por el operador del sistema.
