One of the main challenges in building a Solar Power Generation System at home or a Home Solar Power Plant (Home SPP) is choosing component specifications according to price. The main components of Home SPP are photovoltaics (PV) panels, inverters, and wiring systems. Given the strict price constraints, the selection of parts available on the commercial market is generally of low quality. However, low-quality components can still provide a significant advantage by optimizing the plant design. This research proves that the proper configuration can reduce electricity bills by 52.2%. This configuration does by choosing a Grid Tie Inverter (GTI) with a high working voltage and a 12 Volt PV configured in a parallel series circuit to work at 24 Volts. In addition, the 12 Volt PV panels configured in series to 24 Volts are proven to increase the conversion efficiency.

En años recientes, las microrredes han logrado un considerable desarrollo debido a que representan una alternativa técnica para responder a contingencias en la red de distribución, como también a incrementar el nivel de generación distribuida, entre otros beneficios. Por tal motivo, el presente artículo presenta un modelo de gestión energética basado en sistemas multiagentes para microrredes que operan en modo isla. El objetivo de esta investigación es el diseño de un sistema multiagente que permita gestionar el funcionamiento de un conjunto de microrredes distribuidas en un entorno aislado, además de mantener la correcta conexión con el bus común que une todas las microrredes, el sistema multiagente debe evitar sobrecargas y descargas profundas en las baterías. La metodología implementada es de tipo empírico analítica, la simulación comienza con una revisión del estado del arte, en búsqueda de una estrategia que permita coordinar un sistema de microrredes compuesto, donde estas están conectadas al mismo sistema de distribución operando en modo isla. La simulación del sistema se realizó mediante OpenDSS-G y Python. Los resultados obtenidos sugieren que un sistema de gestión de energía descentralizado, basado en la teoría de sistemas de agentes múltiples, puede tener importantes beneficios como, por ejemplo, el carácter autónomo de las microrredes para la generación de energía en zonas no interconectadas. Finalmente, con la teoría de multiagente se pueden crear sistemas de generación distribuida más confiables debido a su capacidad autónoma de toma de decisiones, para cubrir demandas eléctricas desde microrredes vecinas y conjuntamente prevenir sobrecargas y profundas descargas en las baterías.

“…In summary, the transition of a PMG to an HMG includes several stages. These stages are respectively as: 1) the SEC defines the optimal decision variables and transmits this information to the relevant local controllers of BESSs, DGs, NDDs, loads and ISSes through a communication link; 2) the local controllers take action to adjust their power exchange by modifying their controllers' set-points such that their power generation or consumption matches that defined by the SEC; 3) if the coupling of MGs is also required, the local controller of the ISS will use a suitable synchronization technique (such as the one proposed in [60]) to facilitate the correct sequence of the closing of ISSes, to provide a smooth power transfer from one MG to another.…”

Remote and regional areas are usually supplied by isolated and self-sufficient electricity systems, which are called as microgrids (MGs). To reduce the overall cost of electricity production, MGs rely on non-dispatchable renewable sources. Emergencies such as overloading or excessive generation by renewable sources can result in a substantial voltage or frequency deviation in MGs. This paper presents a supervisory controller for such emergencies. The key idea is to remedy the emergencies by optimal internal or external support. A multi-level controller with soft, intermedial and hard actions is proposed. The soft actions include the adjustment of the droop parameters of the sources and the controlling of the charge/discharge of energy storages. The intermedial action is exchanging power with neighboring MGs, which is highly probable in large remote areas. As the last remedying resort, curtailing loads or renewable sources are assumed as hard actions. The proposed controller employs an optimization technique consisting of certain objectives such as reducing power loss in the tie-lines amongst MGs and the dependency of an MG to other MGs, as well as enhancing the contribution of renewable sources in electricity generation. Minimization of the fuel consumption and emissions of conventional generators, along with frequency and voltage deviation, is the other desired objectives. The performance of the proposal is evaluated by several numerical analyses in MATLAB Ò .
