Proposal for a Monitoring and Dispatch System for Distributed Micro-Generation of Renewable Energy in Virtual Energy Centers

ABSTRACT The creation and updating of ANEEL (National Electricity Regulatory Agency) regulatory resolution on distributed generation provided a new business environment for the electricity sector, as well as enabling consumers to generate energy. In this context, distributed microgeneration plants management is a challenge, mainly for electric power distributors and for the entire supply chain and services. In this sense, it is urgent to develop a monitoring and dispatch system in microgeneration plants, in order to optimize the capacity factor of the enterprises and to enable the creation of Virtual Power Plants (VPP). VPPs are part of a new dynamic of the energy sector's strategic environment, which strengthens distributed generation through smart meters capable of communicating with operational centers and thus influencing new business models already diffused by the known smart grids. Included in this scenario, this paper presents a proposal for a monitoring and dispatch system for distributed micro-generation of renewable energies, as well as the engineering solution for a final product focused on market expectations.

Generation of Photovoltaic Solar Energy. Evaluation of the Demand Curve with the Insert of Grid-connected Photovoltaic Power System at CINDACTA II, Curitiba-PR, Brazil

ABSTRACT Unlike some countries, Brazil has a predominantly hydraulic energy matrix, a clean and renewable source. But, in recent years, both the non-renewal of the normal volumes of water in the reservoirs and the lack of consciousness in the consumption of water and energy have placed the country in a critical state of energy supply leading to many intensive policies to reduce its consumption. In contrast, energy from Photovoltaic (PV) on-Grid Systems has grown dramatically in recent years. In this sense, this study presents an analysis of the contribution of the energy generated by a PV on-Grid Systems to be installed in CINDACTA II, in order to make re-contracting a lower demand possible and also reduce electric energy consumption and its cost.

Assessment of the Potential Implementation of Solar Energy Generation in State Schools in Curitiba/PR

ABSTRACT Solar energy as a form of electric power generation is gaining ground in Brazil, being the subject of worldwide discussions on sustainability. The electric energy, a right of all citizens, represents a consumption of natural resources on a large scale. State schools in Paraná invested more than R$ 46 million to guarantee electricity and thus provide essential running conditions to the system in 2016. Through open data, 15 schools from "Regional Administrativa do Cajuru", in Curitiba/PR, were evaluated in consumption and expenses of electric energy from January to May of 2017 and a solar photovoltaic system was dimensioned to supply the demand of each school. From that, it was estimated the total saving from the electricity that would no longer be spent on electricity which could be directed to other educational programs and projects of interest to the community towards sustainability within the school. The savings estimated totalized more than R$ 435 thousand annually.

Solar Energy for Residential Use and Its Contribution to the Energy Matrix of the State of Paraná

ABSTRACT The present study evaluates the economic viability of the application of solar energy for electric power generation via the use of photovoltaic systems in a residential consumption unit in the city of Curitiba. Since the energy from the sun is abundant, clean, renewable and has the potential to compete in productivity and profitability, the evaluation of the applicability of these systems in homes, not only in industrial parks, is of great interest. A household with the determined consumption profile was chosen for this case study through simulations with the HomerPro software. After analyzing the data, the photovoltaic potential of the State of Paraná was estimated to investigate the possibility of photovoltaic generation growth in the state energy matrix and its consequences.
