Dynamics performance of the wind-power supply chain with transmission capacity constraints

Previous studies have shown that poor performance of energy supply chains arises from incorrectly interpret feedback information and time delays between decisions and actions in energy policy. This paper assesses alternatives to improve performance of wind-power supply chain with transmission constraints that contribute to enhance response capacity of the wind industry to changes of energy policy. In order to test these alternatives, this paper used a simulation model with system dynamics (SD), taking as case study Brazil. The simulation model represents the main time lags and fluctuations that exist in the wind-power supply chain. Four simulation scenarios were proposed to evaluate changes in auction-based policy in wind industry of Brazil. The results are related to operational capacity, inventory levels and response capacity. This paper provides an analysis of different scenarios that contribute with synchronization of auctions policy, including transmission capacity constraints

Modeling Alternatives Sustainable-Energy-Policy for the Supply Chain of Wind Power in Brazil.

Renewable energy studies have received high attention in the last few years due the increasing deployment of alternatives such as wind, solar and biomass, as a result of the urgency in reducing fossil fuels consumption. This situation has involved an important challenge for long-term renewables policy and energy system planning. Brazil is the richest country in terms of renewable sources in Latin American. Brazil has energy generation portfolio not much different form the Colombia one, and the understanding of this very important country will contribute to inspire other countries in the region, particularly Colombia. Since 2004 the Brazilian energy policy promotes wind power development aimed at complementing hydropower generation. Despite the energy policies adopted in Brazil, the supply chain of wind power has experienced barriers that include: insufficient transmission lines and the delays in energy projects caused by lack synchronic among the energy policies. Thus, the unsynchronised energy policy has affected the performance of renewable energy supply chain, which has produced an impact on the electricity market. This thesis addresses these issues by evaluating alternative sustainable energy-policy, which must reflect new institutional guidelines to support wind power penetration and their dynamics performance in supply chain
