According to the European Photovoltaic Industry Association, the world capacity of photovoltaic (PV) generators exceeded 130 GW in 2013. In Brazil, the incentives to the connection of micro and mini distributed generators to low voltage networks represent a strong indicative of the potential rapid growth of renewable sources in Brazilian electricity market, specially the photovoltaic generation. Several aspects contribute to this new scenario such as: (a) the publication of resolution #482/2012 by the Brazilian Electricity Regulatory Agency (ANEEL); (b) the falling prices of this technology; (c) the advent of specialized industries with qualified labours; (d) outstanding solar irradiance levels; and (e) the increased risk of power rationing in next years. Although several countries present high penetration level of PV generation, as Germany, for example, one must consider that their experiences cannot only be transferred to the Brazilian scenario from technical, economic and social perspectives. Regarding the economic aspects, for example, different compensation/payment systems can be adopted. Germany adopted the feed-in-tariff system while Brazil adopted the net-metering system. These differences strongly affect economic and energy markets. In this context, this project intends to develop new methods to determine the influence of photovoltaic generation in the projection of utilities future demand in the medium- to long-term future. The investigated methodologies are based on the utilization of real measurements data from Canada, USA, United Kingdom and Brazil, on statistic techniques, e.g., Monte Carlo, and on the employment of sequential power flow solutions (time-series or multi-stages).
