A flexible metamodel architecture for optimal design of Hybrid Renewable Energy Systems (HRES) – Case study of a stand-alone HRES for a factory in tropical island

Abstract

The energy sector is mutating with an increasing share of renewable energy. Renewable energy de velopers are facing new challenges, in particular sizing systems that combine multiple production sources and storage devices to match demand. Accordingly, this paper proposes a flexible metamodel architecture and a Cþþ software implementation for the grassroots design of Hybrid Renewable Energy System (HRES). The metamodel enables one to build optimization problem formulated as a Mixed Integer Linear Problem (MILP) with a tailor made objective function to find the optimal size of HRES. The flexibility of the metamodel lies in its ability to handle many hybrid system configurations for three common types of usages of HRES, either for onsite demand, remote demand or a combination. It is demonstrated with two specific case studies, a stand alone HRES composed of PV panels, battery set, and a diesel generator; and a factory in a tropical island. This paper contributes to a better adoption of cleaner production systems since it provides to decision makers a tool for HRES assessment.

“…In case 2 of Figure 1 storage can be needed to balance renewables production. In Roth et al, (2019) we have proposed a flexible meta-model architecture of HRES has been proposed and it was further specified for the grass root design of a stand-alone HRES for a factory in tropical island. We have then…”

“…Rigo -Mariani et al, 2017;Scheubel et al, 2017. To some extent, MILP models are inaccurate due to the linear modelling they involve, but it is acceptable in the case of grassroots design as we have shown in Roth et al (2019). In both categories of optimization techniques that we cited, one can perform mono-objective or multi-objective studies (Eriksson and Gray, 2019).…”

Like others, we have previously stressed out the current exaggerated investment cost of battery storage that makes their use unprofitable nowadays (Roth et al, 2019). Hence, we have disregarded any storage here in order to focus discussions on self-consumption regulation framework.…”
