Optimal Strategy of the Energy Management Within the Microgrid Using the Hydrogen Fueled Gas Turbine

The hydrogen production by means of renewable energy exploitation has the potential to address issues that arise when an increasing share of power is generated from sources that have a highly variable output. Although these systems have been widely studied, one of the key aspects to be considered is the choice of the energy management strategy. The aim of this paper is to define and present an optimal strategy for the energy flow management of a pilot plant consisting of a turbine gas facility making use of power produced during turbine tests — along with solar — for hydrogen production integrated with batteries storage. Key results from the analyses are: i) increasing the hydrogen production target, the hydrogen production ratio increases up to a maximum value equal to about 100%; ii) optimizing the management strategy, the system is always able to meet the demand of hydrogen; iii) with a larger hydrogen storage capacity, the microgrid is able to exploit a higher amount of renewable production, achieving the total renewable energy exploitation.
