This paper makes a comparison of distributed generation allocation in distribution networks using two algorithms based on Genetic Algorithms: the Compact Genetic Algorithm (CGA) and the Chu-Beasley Genetic Algorithm (CBGA). The operations conditions of the network are verified through the backward/forward sweep method. The objective function considered in the optimization model aims at minimizing of total active power losses in the system. The specialized algorithms are tested with three electrical systems: 10-bus, 34-bus, 70-bus and 126-bus and the obtained results show the convergence quickly and the robustness of the implemented algorithms.

The increase in wind generation connected to power systems has caused changes in the power system characteristics. This increase has raised a concern related to the system frequency response after a disturbance, since the wind turbine generators do not present an inherent inertia response. As a result, different system operators around the world require a synthetic inertia from wind farms (WF). In this work, an analysis of the frequency support performed by wind farms, composed of doubly fed induction generators (DFIG) wind turbines, is performed. Simulations are carried out in ANATEM, a CEPEL software, using a modified version of the Western System Coordinating Council (WSCC) test power system. The simulations comprise different operating conditions and allows evaluating the wind farm contribution to improve the system frequency after a disturbance.

Over the years, there has been a significant increase in the number of photovoltaic installations, this is due to the innovation of the electric sector based on new regulations, government incentives and more accessible technologies. However, the vast majority of existing low voltage networks were not expected to absorb a large volume of distributed generation, mainly residential feeders, which generally have low demand during the day, when photovoltaic generation reaches its peak production, which it can cause a reversal of the energy flow in the feeder, resulting in a series of technical losses for the energy distributors. This article presents a method using Monte Carlo Method (MMC) to analyze the losses associated with high photovoltaic insertion in secondary distribution networks, in order to guarantee quality electrical energy, without jeopardizing the expansion of photovoltaic generation. To perform the simulations and allocations, the algorithm is implemented in Python programming language, which uses the OpenDSS COM interface for power flow calculations.
多年来，光伏装置的数量显著增加，这是由于电力部门在新法规、政府激励措施和更容易获得的技术基础上的创新。然而，绝大多数现有的低压电网并没有期望吸收大量的分布式发电，主要是住宅馈线，白天通常需求较低，当光伏发电达到峰值时，它会导致馈线中的能量流逆转，给能源分销商带来一系列的技术损失。本文提出了一种利用蒙特卡罗方法(Monte Carlo method, MMC)分析二次配电网中光伏高插电损耗的方法，以保证电能质量，同时不影响光伏发电的扩展。为了进行仿真和分配，该算法采用Python编程语言实现，并使用OpenDSS COM接口进行潮流计算。

This paper presents a sustainability aspects evaluation of power line routing, considering environmental and socio-economic impacts within the Brazilian expansion planning context. The Transmission Line (TL) Osório 3 - Gravataí 3 located in Brazil is evaluated as study case, and an alternative route is proposed using map algebra and Least Cost Path Analysis (LCPA). Sustainability indexes are calculated for original and alternative TL route based on the methodology presented by the Energy Research Office (EPE), one of the government companies responsible for energy expansion planning in Brazil. The evaluation result is that the proposed route modification increased the TL sustainability index from 0.67 to 0.71, however, increasing the total line length in 23 km.

Renewable generation has gained relevance worldwide in the production of electricity. Mechanisms such as feed-in tariffs have made investment viable in this type of technology. However, in the medium term these technologies will be competitive, and these promotion mechanisms will gradually be phase out. On the other hand, reducing the intermittency of these plants requires economic incentives. This paper proposes a complementary economic incentive for Renewable Energy Resources (RER) production, aimed at increasing their production in the electricity market taking into account their probability of meeting the dispatched energy requirements. This methodology was tested for solar and wind plants that actually operate in the electric power system of Peru, considering three different demand scenarios. The proposed economic incentive constitutes an alternative to promote the investments to increase the reliability in the production of renewable energy sources especially, for the technologies who have reached competitive market conditions.

This article presents the feasibility of Hydrogen usage when applied as an energy storage technology. In this sense, a system was implemented, which consists of Photovoltaic (PV) panels that feed a specific load, whose operation obeys a residential consumption profile. With this, it analyses the behavior of all the storage elements, both considering the absorption of excess energy produced by the PV system, as well as its activation to supply the load demand in moments of solar energy generation absence. The performed tests consider an annual period, taking into account the yearly solar irradiation in the southeastern region of Brazil.

The popularization of electric vehicles (electric vehicles (EVs)) is becoming an unstoppable trend in modern society. Thus, efficient simulation tools that can predict the EV operation and deployment are significant assets for charging point operators (CPOs), electric mobility service providers (EMSPs), charging service providers (CSPs) and electricity companies. In this paper, an algorithm for simulating the utilization and availability of public EV charging stations (CSs) has been developed. Based on several EV user features, the proposed algorithm generates realistic scenarios of CS availability, utilization, and impact over the distribution network via AC power flows. Moreover, the impact of considering smart charging (i.e., remote CS power limit control) and price policies is also modeled by the proposed algorithm. With these enhancements, the proposed simulation tool is used to predict the aggregated behavior of a population of EV users within the vicinity of two real distribution feeders. Results show the capacity of the proposed algorithm to generate realistic CS utilization statistics subject to different smart charging and price policies.

Here is presented a model for the optimal sizing and operation of a domestic installation with photovoltaic generation (PV), battery storage, electric vehicle (EV) and connection to the grid under different tariffs. The key point is to assess the effect of different commercial tariffs on the system optimal size and total cost. Three kind of tariffs are considered, each one oriented to: i) only grid connection, ii) prosumers, and iii) users with EV. Modified tariffs considering prosumers and EV are explored. The model is posed as a linear two stage stochastic optimization problem with uncertainty in PV generation and demand. In the case study it is applied to three real tariffs in Spain and a sensitivity analysis is performed on: PV cost, battery cost, and price for the PV generation sold to the grid.

This article presents an extension of the classic fast decoupled algorithm oriented to the solution of the load flow of isolated microgrids with droop control. Microgrids in isolated operation have a series of characteristics that limit the application of conventional methods for calculating the load flow, such as the absence of a reference bus, floating frequency, and the presence of droop generation control. In this article, the classic fast decoupled load flow algorithm is modified and extended to weak, isolated microgrid applications with droop control. The performance of the algorithm is investigated using a 38-bus test system.

This paper presents a power balance control strategy for an off grid DC microgrid. It is composed by a photovoltaic system, storage system and an electronic load. In this type of system, when the power available from the photovoltaic arrangements is larger than the load demand, the excessive power generation leads to overvoltage on the DC bus. Besides that, due to the partial shading of the PV panels, the DC bus can become dynamically unstable. So, a power balance control (PBC) strategy is used to stabilize the system and avoid overvoltage problems. To achieves such a goal, the implemented topology provides two DC bus voltage levels, 150 Vdc and 300 V dc, where the first is responsible for the power transfer between the PV and the battery and the second is provide for the power transfer to the load. The algorithm monitors the power level generated by the PV and the load's energy demand and constantly balances the power generation and consumption with the help of an electronic load control. Simulation results are presented to validate the proposed strategy.
