We take inspiration from the Modern Portfolio Theory introduced by Markowitz to propose a simplified strategy\u00a0for the portfolio management of renewable energy sources based on Gaussian fluctuations with tunable correlations.<\/p>\n

By analysing the impact of production fluctuations, we show how \u2013 depending on the sources’ temporal\u00a0correlation patterns \u2013 a careful geographical allocation of different types of renewal energy sources can reduce\u00a0both the energy needs for balancing the power system and its uncertainty. The proposed strategy can be easilyintegrated in a decision support system for the planning of renewable energy sources. Therefore, providing \u00a0policy\/decision makers with an additional tool. We test our strategy on a set of case studies including a real-case\u00a0based on literature data for solar and wind sources, and discuss how to extend the computation to non-Gaussian\u00a0sources.<\/p>\n

The paper shows that in the Markowitz framework an efficient trade-off between production and \u00a0fluctuations can be easily achieved, and that such framework also leads to important considerations on energy\u00a0security. In perspective, analysis of time series together with such enriched frameworks would allow for the\u00a0analysis of multiple realistic renewable generation scenarios helping decisions on the optimal size and spatial\u00a0allocation of future energy storage facilities.<\/p>\n
