“…This system was also considered in [7,[9][10][11], and it represents a typical case of DG optimization planning. It consists of one 132 kV/33 kV substation (40 MVA capacity) at bus 9 to serve eight aggregated loads (33 kV/11 kV service transformers) at buses 1-8 under normal operation conditions.…”

“…The above theses choose losses to serve as object function, and cannot formulate a scientific model to assess the effects of implementing DG in distribution systems. In [7][8][9][10], the theses construct multi-objective mathematical models, but they convert the multi-objective function into the single objective function, a method that not only omits the relationship among objectives, but also results in the absence of a comprehensive optimization perspective to find the global optimal result. In [11,12], though the theses build reasonable multi-objective functions, they lack a systematic optimization method to handle multi-objectives.…”

Based on Game Theory and Multi-objective optimization problems (MOP), Game Optimization Theory (GOT) is discussed in this paper. Optimization Stability Analysis (OSA), Distance Entropy Multi-Objective Particle Swarm Optimization (DEMPSO) and Fuzzy Multi-weights Decision-making Method (FMW) are proposed as well. Game Optimization Theory, which is a comprehensive system, could not only handle multi-objective optimization problems effectively, but also could offset the disadvantages of traditional optimization theories, such as lack of framework and the insufficient consideration of relevant elements. In this paper GOT is used for the first time in solving the distribution systems planning (DSP) issue by implementing distributed generation. The proposed model integrates costs, losses, and voltage index to achieve optimal size and site of distributed generation. The model allows minimizing total system costs, system power losses and maximizing voltage improvement. A detailed DSP example is used for verifying the effectiveness and reasonableness of GOT in this context.

“…Son restringidos a la hora de aplicarlos a problemas reales, debido a la alta complejidad que presentan; sin embargo, son eficientes en problemas sencillos. Para solucionar el problema de GD en el SD, los métodos más utilizados son [34]: programación lineal [40], programación no lineal [41], programación dinámica [42], programación entera [43] y programación estocástica [44].…”

La generación distribuida (GD) se presenta como un apoyo para suplir la demanda del sistema de forma localizada, lo que permite además como alternativas de generación el uso de fuentes de energía renovables a pequeña escala. Como aporte principal, este artículo presenta las consideraciones que se deben tener en cuenta al momento de analizar, modelar y solucionar el problema de ubicación y dimensionamiento de GD en la red eléctrica de distribución. Inicialmente, se enuncian los aspectos técnicos de la red, el modelado de las cargas e impactos de la GD; seguido de la formulación del modelo matemático del problema, principales técnicas de solución y metodologías aplicadas en la literatura; finalmente, se muestran las investigaciones futuras en este campo de estudio. Todo lo anterior en busca de mejorar las condiciones operativas de la red. Dentro de la revisión de los trabajos presentados por los diferentes autores, se encontró que una gran parte de los estudios se enfocan en los aspectos técnicos, sin tener en cuenta los costos asociados a la integración de GD, ni los incentivos económicos a los que puede ser susceptibles este tipo de proyectos, que son de vital importancia para evaluar la viabilidad de la propuesta de integración.

Abstract:In this paper, the problem of optimally placing shunt capacitors and generators in radial distribution systems is handled and a new calculation technique based on wavelet neural network (WNN), which is computationally effective compared to well-known techniques, is proposed. The objectives for the proposed method are simply selected as the minimum cost of peak power and losses and maximum voltage stability. The suggested optimization technique is tested on various IEEE radial buses and then compared to the well-known methods in the literature, i.e. golden section search, grid search, and Acharya's heuristic method. The proposed and conventional methods are applied to well-known IEEE buses to see the performances of the suggested technique. The results demonstrate that WNN provides an efficient solution to the placement of both shunt capacitors and distributed generators for power distribution systems.
