Economic Viability of Residential PV Systems with Battery Energy Storage Under Different Incentive Schemes

Abstract: The high penetration of distributed renewable energy sources (DRESs), and especially photovoltaics (PVs), in LV distribution grids questions their safe and reliable operation. In this context, battery energy storage (BES) systems can be an effective solution to reduce the intermittency of electricity generated by DRESs and to enhance the resilience of power systems. However, it is unclear how different incentive schemes and regulatory frameworks affect the BES profitability for prosumers, compared with no incentives at all. In this paper, a techno-economic model is developed to investigate the economic viability of BES for residential PVs, operated under different incentive schemes. The input parameters of the model include typical load and generation profiles, electricity prices as well as typical PV and BES costs. Using these data, an optimization procedure based on an exhaustive search is performed and the optimal size of the integrated PV-BES system is derived.

Total factor productivity and sustainable agricultural development

Abstract: Total factor productivity (TFP) growth is a widespread quantitative economic instrument used to evaluate the performance and sustainability of agricultural systems over time, which has proven valuable for policy measures geared towards fostering agricultural development. Yet, there are more dimensions to be accounted for when aiming for sustainable agricultural development than the production side of an agricultural system namely, the issues of environmental protection and resource use together with the question of social responsibility. Consequently, objections have risen in the recent decades, regarding the suitability of TFP growth to reveal whether a rural system is progressing in a sustainable course and alternative tools that attempt to remove the bias in measuring changes in productivity have been proposed. The objective of this paper is twofold; to review the conventional approaches in the measurement of TFP growth and to discuss the necessary amendments in TFP measurement so that it can be a more comprehensive index of sustainable growth and thus conducive to agricultural development. The amendments which incorporate externalities and resource quality issues in productivity measurement, produce alternative measures to TFP namely, ‘total resource productivity’ and ‘social’ total factor productivity. Another approach is to construct sustainability and productivity indices separately, and then join them together so as to broaden the evaluation of agricultural systems.
