Optimal sizing of hybrid power plant

Abstract:
Hybrid Power Plants combining renewable assets attenuate the unpredictable nature of renewable sources, therefore enhancing their benefits. A Hybrid Power Plant combining wind and solar generators with battery energy storage system is analyzed in this thesis. The objective is to determine the rated capacities of the technologies which yield the maximum revenue stream while ensuring a feasible investment. Therefore, a mathematical model to maximize the Net Present Value (NPV) is implemented. Electricity price profiles, power time series and costs are the parameters affecting the energy arbitrage of the battery, the anti-correlation between wind and solar resources and the installation ratio between the capacities. The sizing optimization is applied to an Indian case study, considering specific wind and solar resources and Power Purchase Agreement conditions. Technical and economical parameters are analyzed to assess the synergies of the technologies involved. Cost decrease, reduction of renewable sources intermittency, capacity factor and revenue increase are the main benefits observed. Different scenarios are considered in order to compare these aspects. Finally, a sensitivity analysis is carried out to estimate the uncertainties involved in the model.
