Modeling Long-term Variability of Renewable Energy in Generation Planning

• Long term variability of solar and wind generation including inter- and intra-annual variability, as well as contingencies around low solar/wind availability periods are typically ignored in generation planning. This study explores planning methodology to capture long term variability including the computational challenges such a model presents. We use a case study for Guinea-Bissau - a small country in Africa transitioning from thermal to potentially high solar penetration in future. We show that long term variability and renewable contingency planning may have a strong impact on the selection of solar PV in such cases. We also show that batteries can increase the economic viability of solar PV in light of the inter-annual variability.
