Optimized battery sizing for merchant solar PV capacity firming in different electricity markets

Abstract

This work analyses the minimum energy capacity requirements to be demanded to battery energy storage systems used in megawatt-range merchant solar PV plants to grant capacity firming. The operation of such a plant is simulated (with a 2-minute time step, at three different locations of the Iberian Peninsula, and for different battery sizes) after solving a quadratic programming optimization problem. The control algorithm takes into account the irradiance forecast and the intraday electricity market configuration, which presents certain peculiarities in the Iberian region with regard to other European markets. The analysis has been performed in an annual basis and current irradiance measured values have been used.

Battery size determination for photovoltaic capacity firming using deep learning irradiance forecasts

“…This MA is operated by OMIE and OMIP in coordination with the Spanish and the Portuguese TSOs. Once consolidated, MIBEL considered in 2010 2011 the possibility of modifying its intraday market structure to increase the number of sessions (from six to eight) and to reduce lead times (fixed in 135 minutes at that time) to 75 minutes [54,55]. The initiative was rejected due to the beginning of movements towards a European integrated internal electricity market.…”
