In this article, the problem of allocation of photovoltaic generators in a distribution network while losses are minimized considering network operating constraints is formulated and solved. Three formulations are considered. In order to take into account adequately the imbalance of distribution networks, a three-phase approach is considered. To solve the three formulations a stochastic algorithm based on an evolution strategy is used showing good results in minimizing technical losses. The results obtained illustrate the proposals and their practical use.

The main objective of this work is to illustrate a cost-effective smart meter. It is designed to measure the demand's power consumption and support the new requirements for operation and control functions in the distribution networks. Also, we propose and implement a novel DR program for this SM. The smart meter can be used as energy meter or as power quality meter (10 seconds, average). Based on open source technologies, it offers a plurality of communication possibilities, like USB, Ethernet, ZigBee or WLAN (802.11n). Additional calculations can be done within the external central system (DR Manager).

Sustainability of microgrids depends on a successful business model, enabling technology, and regulation policies. Technical challenges are still significant, but they can be divided and solved in diverse levels with application of existing technology in several ways. However, the regulatory context is vital to incentive microgrids integration into the electricity market. This article aims to explore and categorize different regulatory challenges existing nowadays in Brazilian scenario, in order to identify them, propose possible solutions and encourage investment in microgrids. The main conclusion is that, in general the regulatory environment in Brazil is adapting to include microgrids in the electric system. Though, some regulatory difficulties tend to be solved with the implementation of regulations relating to micro-generation that can be subsequently applied to microgrids and through benchmarking with international experiences from other countries.

This paper proposes a way to promote wind energy in countries that have not developed a considerable percentage. To get results, a calculation methodology based on levelized cost of energy is proposed, and then an incentive through payment for firm energy of wind farms. By introducing forms of renewable generation, the system is diversified, resulting in a smarter electricity mix. At the end of the work, a case study is presented, with the results for a chosen scenario, where is possible to check the proposed methodology.

The appearance of new concepts in power systems, such as, smart grids and microgrids brings several advantages. This includes the use of distributed generation and the execution of demand response programs. However, their implementation can also bring management and stability problems. The system presented in this paper allows the real-time simulation of microgrids using real generation and consumption resources. The proposed system can follow real profiles and reply them into the simulation by using real loads and wind generation. The focus is given to the control of the resources in each desired consumption and generation requirement. The case studies use a real consumption profile of a residential house, small commerce facility and a real profile of a home-scale wind turbine. The use of real loads gives a more reliable simulation.

In this paper we describe an algorithm that involves linear programming (an exact optimization technique) and Monte Carlo Simulation for solving the middle-termed hydrothermal coordination. The proposed model considers uncertainties of wind and hydrology, as well as the effect of pump storage hydro-power units.

Demand side management (DSM) programs aim at reducing energy consumption on the demand side, which benefits both consumers and utilities. These programs could also help maintain the critical balance between generation and demand in isolated microgrids. In this case, demand is a treated as a significant uncertainty in the context of dispatching the power resources of a microgrid. Thus, in this paper the uncertainty of consumer response to DSM signals are treated as intervals to represent the corresponding range of variation based on affine arithmetic. The total range of total grid consumption is taken as the sum of intervals in each house, using data obtained through surveys regarding usage of appliances to obtain the individual consumer intervals. The proposed affine arithmetic model is then applied to the prediction of possible range variation in a one-day ahead load forecast. Finally, the presented technique is demonstrated using data obtained in an actual microgrid deployed in Huatacondo, Chile.

An interleaved boost topology suitable for multistring photovoltaic topologies is presented in this paper. The presented topology allows to use independent and decoupled Maximum Power Point Tracking algorithms in order to optimize the use of the solar energy, especially for large PV farms, where the special location of the panels is distributed. The main features of an interleaved structures are presented and why they are adequate for connect several PV modules is explained. A basic Perturb and Observe algorithm is used to achieve the Maximum Power Point of the PV strings and its extension for the proposed topology is presented. Several simulations were carried out to demonstrate the suitability of the interleaved boost topology for PV applications.

Lately, the development of the Electric Vehicle (EV) has become a strategy to soften the collateral damages of the environment pollution. However, the forecasts of a wide EVs deployment, establish a stress that has to be carefully analyzed in distribution systems. Whereby, the need arises of researching respect to the effects of EVs on electric grids since different perspectives. This paper presents a review of the last forty years around the interaction of EVs and distribution systems. Several works have been reported, considering diverse trends: the power quality, ancillary services and the participation of EVs in electricity markets, among others.
