“…In a PV module, PV cells are connected in a series and parallel configuration, depending on the voltage and current rating, respectively [1]. In recent times PV based energy is gaining prominence due to the advances in the PV cells [3,4], lowering PV cells cost [5], and government incentives [6][7][8]. Compared to any other renewable energy-based power source, PV is considered portable and easy to use [5].…”

A Photovoltaic (PV) cell is a device that converts sunlight or incident light into direct current (DC) based electricity. Among other forms of renewable energy, PV-based power sources are considered a cleaner form of energy generation. Due to lower prices and increased efficiency, they have become much more popular than any other renewable energy source. In a PV module, PV cells are connected in a series and parallel configuration, depending on the voltage and current rating, respectively. Hence, PV modules tend to have a fixed topology. However, in the case of partial shading, mismatching or failure of a single PV cell can lead to many anomalies in a PV module’s functioning. If proper attention is not given, it can lead to the forward biasing of healthy PV cells in the module, causing them to consume the electricity instead of producing it, hence reducing the PV module’s overall efficiency. Hence, to further the PV module research, it is essential to have an approximate way to model them. Doing so allows for understanding the design’s pros and cons before deploying the PV module-based power system in the field. In the last decade, many mathematical models for PV cell simulation and modeling techniques have been proposed. The most popular among all the techniques are diode based PV modeling. In this book chapter, the author will present a double diode based PV cell modeling. Later, the PV module modeling will be presented using these techniques that incorporate mismatch, partial shading, and open/short fault. The partial shading and mismatch are reduced by incorporating a bypass diode along with a group of four PV cells. The mathematical model for showing the effectiveness of bypass diode with PV cells in reducing partial shading effect will also be presented. Additionally, in recent times besides fixed topology of series–parallel, Total Cross-Tied (TCT), Bridge Link (BL), and Honey-Comb (H-C) have shown a better capability in dealing with partial shading and mismatch. The book chapter will also cover PV module modeling using TCT, BL, and H-C in detail.

“…La penetración de la energía solar fotovoltaica en los sistemas de distribución actuales puede ocasionar diversos efectos, los cuales han sido abordados en estudios [4]- [6] que describen y cuantifican la variación de factor de potencia, perfiles de tensión, potencia activa y reactiva, desbalance y distorsión armónica, entre otros.…”

“…Hallaron que las pérdidas de energía se veían afectadas por la ubicación de los SFV y que había una reducción en la carga del alimentador a partir de la integración. Singh et al [6] analizaron el impacto de la integración de SFV en una red de distribución IEEE de prueba de 13 nodos en términos del rendimiento de voltaje y las pérdidas en el sistema. Encontraron que bajos niveles de integración repercutían positivamente en la red al mejorar el perfil de voltaje y reducir las pérdidas globales de energía.…”

Este trabajo presenta el estudio de una red eléctrica de baja tensión en estado estable con inyección de potencia de sistemas fotovoltaicos (SFV), con el propósito de cuantificar el impacto a partir de indicadores asociados al valor eficaz, perfil de tensión, desbalance, pérdidas en los conductores y sentido de flujos de potencia. La red modelada fue estudiada para cinco escenarios de ubicación de SFV y diez porcentajes de inyección de potencia FV (1%, 3%, 5%, 10%, 15%, 20%, 25%, 50%, 75% y 100% de la capacidad nominal del transformador). Se realizó un análisis cuasi dinámico con pasos de una hora durante un año. Los resultados indican que el impacto producido en los parámetros eléctricos analizados depende del lugar y de la capacidad instalada de los autogeneradores FV; los porcentajes de inyección superiores al 50% son desfavorables para esta red en los cinco escenarios

Evaluating the Risk of Exceeding the Normal Operating Conditions of a Low-Voltage Distribution Network due to Photovoltaic Generation

Connecting photovoltaic micro-installations to a low-voltage network changes the operating conditions of the network. As a result, in certain situations, the permissible operating limits may be periodically exceeded. The risk of exceeding the normal operating conditions of the network depends on multiple factors, including the installed capacity of the photovoltaic sources. In this article, we use a time-series method to determine the annual risks of exceeding the bus voltage limits, the rated current of the lines and transformer, and the acceptable limit of the negative sequence component of bus voltage, as well as the risk of a reverse flow occurring, and the risk of energy losses increasing. We calculate these risks for different levels of penetration of the photovoltaic sources, different divisions of the rated power of the photovoltaic sources between individual phases, and different consumer load profiles. We perform calculations on a CIGRE test network using OpenDSS and statistical meteorological data for the Katowice (Poland) weather station. The results obtained indicate that connecting photovoltaic micro-installations to a low-voltage network has the greatest impact on the risk of reverse flow occurring and the risk of energy losses increasing. In addition, the risk of overvoltage and branch overload increases substantially. The method we present allows one to determine the value of the hosting capacity of a given low-voltage network, ensuring that the assumed risk of exceeding the normal operating conditions of the network is retained.
