The power system reconfiguration is a challenging task. As smart grids concepts develop, different approaches try to take advantage of the grid intelligent features and infrastructure to evolve a fast and robust self-healing scheme. At the distribution level, the self-healing schemes are responsible for performing automatic corrective and self-restorative actions. This task includes managing the service restoration by locating and isolating the fault, and reconfiguring the network topology to decrease the harm. This paper presents a self-healing scheme using Artificial Immune System as an optimization tool to solve the service restoration problem in power systems considering faults within the internal switch breakers. To make this approach suitable for bigger systems, the Prim Algorithm is used due to its capacity to generate minimum spanning trees from a graph. The proposed scheme is tested on benchmark systems to investigate the capacity of proposing feasible solutions for faulted systems.

In electric power systems there are contingencies that can cause overload of any equipment, angular and voltage stability problems and frequency stability issues due to imbalances between load and generation. Most of those contingencies require disconnecting load to ensure the stability of the system and the integrity of the equipment. In most cases disconnection should be performed so quickly that it is possible only automatically. Such solutions are commonly referred by the acronym RAS, which means “Remedial Action Scheme”. UTE is currently implementing a solution of RAS [1] type to protect the network against the most severe contingencies.

Weather-related impacts are at the top of all outage causes. Yet, traditional outage management (OM) approaches do not integrate all available and relevant weather-associated data automatically. This paper presents a predictive method that correlates different weather-associated data layers to provide predictive OM process implemented using the geographic information systems (GIS) framework. Examples for both transmission and distribution OM are demonstrated using vegetation, wind, and power system data in ArcGIS.

This work presents a geospatial computational tool-GeoLCOE-for estimating the levelized cost of energy (LCOE) of multiple power generation technologies in Colombia. This tool is designed for assessing both economically and technically new generation projects across the Colombian geography. This tool computes the LCOE of renewable and non-renewable generation technologies for multiple locations based on geospatial data of energy resources. GeoLCOE allows to identify promising places for the construction of new generation projects. The objective of this tool is to provide the Colombian planner with additional assistance for the generation expansion planning.

This paper presents an stochastic optimal power flow model in order to assess the effect of Time-Of-Use tariffs on load profile. A bottom-up model is used to represent responsive loads. Uncertainty about consumers' preferences are modeled by stochastic variables with their probability density functions. The model uses data from a survey about consumption patterns of residential consumers in Brazil. The Point Estimation Method is used to solve the optimization problem. Results obtained with a 192-bus distribution system are presented.

This work presents the application of an economic model of the electricity market for evaluation of social policies to encourage the use of renewable energy sources in Brazil. With this model it is possible to represent the economic flows of the regulated electricity company and the consumer, resulting in quantitative measurements of consumption, income, price and quality, items needed for the evaluation of socioeconomic policies. The employed methodology will lead to an economic macro analysis of these policies for different classes of residential consumption. As a result, it will be established a connection between the type of consumer and the best incentive policy to be adopted, in order to evaluate its ability to promote socioeconomic welfare and to encourage the effective use of renewable energy sources in microgeneration for different scenarios.

One of the solutions to tackle the problems of high peak demand and grid instability due to high photovoltaic (PV) power penetration is to deploy a battery storage system. This paper presents a real-time battery management algorithm (BMA) for peak demand shaving in small energy communities with grid-connected PV systems. The BMA aims to control the charge/discharge of the community battery storage using measurement of the instantaneous power consumption of the community. Historical data records of community daily energy consumption and available renewable energy are taken into account to manage the charge/discharge of the battery. Simulation results show the effectiveness of the BMA which is able to reduce the peak energy consumption by 35%, increase PV self-consumption by 47% and reduce transmission line losses during the peak period by 56% when compared to a PV system without the battery storage.
