Abstract
The energy planning model H2RES [1] has been used successfully for planning of island and micro grid operations [2], [3], [4], [5], [6]. H2RES has been rewritten with new programming tools, revising the user experience in terms of usability and modelling abilities, while adding new optimization capabilities. Implementation of an Electric Vehicle (EV) module is the next step in the electrification of energy systems [7]. The methodology used to develop the EV module leans on the tested RenewIslands methodology [8] used for island and micro grid energy scenarios . The new version of H2RES solves the problems of the integration of energy systems with a high share of renewable energy sources (RES), and a transport system based on EVs [9]. Since EVs are currently in development, and limited commercial use, there is still insufficient data regarding their use [10]. Therefore, simulations are used to estimate the integration of EVs into energy systems. It is crucial to carefully plan the penetration of new technologies in both transport and energy systems and to determine how the new technologies interact [11]. The aim is to use the developed models to optimize EV penetration in energy scenarios such as a micro grid, consisting of a single vehicle and neighbourhood, to a whole fleet and entire regions. Additional goal is to improve on optimization results of H2RES compared to software packages that use an aggregated battery model for all the vehicles in an energy scenario. The concept for the analysis of EV and RES integration includes a model of EVs in H2RES for the hourly balancing of energy systems. The main addition to H2RES model is the ability to integrate EVs into the energy planning by taking account of the energy price, State of Charge (SoC) of the battery and overall load on the energy system, thereby enabling RES to compensate for the increased demand in the grid. H2RES is able to model EVs in three modes: Dump Charge (DC), Smart Charge (SC) and Vehicle to Grid (V2G). Each mode poses a different set of rules and constraints on the energy system. The batteries are modelled as a single unit where they represent a group of EVs considered in the scenario. For test purposes, a simple case study of the island of Mljet and DC mode was calculated with 7 EVs and generic driving cycles with daily demand of 63 kWh. Yearly electrical demand for scenario was increased by 8%. All of the mentioned improvements and features were tested in a case study for the Dubrovnik region and compared to results obtained in similar energy planning tools. The results of the case study are presented in this paper.
