Building upon the results of previously published studies within the scope of the REACT project and leaning mainly on Deliverable 1.1 Pilot technical characterisation and regulatory framework and Deliverable 2.1 Assessment of RES potential at pilot sites, this report aims to take into account as many legislative, economic and technical limitation into account as possible and, powered by novel modelling solutions, provide simulations that would facilitate long-term multi-criteria sizing analysis that are to follow in the following tasks of the project.
This deliverable first provides a brief summary of techniques that are used in system modelling (game theory, linear optimization, etc.) and a rundown of some of the most popular available software solutions for these simulations. The very process of simulation, presented after the initial state of the art review, is conducted and aided with relevant parameters with the main goal of monitoring the performance of the energy transmission and dispatching of various power systems with the main goal of achieving self-sustainability and economic viability, but also tracking the impact that high renewable penetration might have on the stability and limitations of the existing power transmission system. With each considered island being a specific use case and their parameters varying significantly, this report takes into account differences in climate through distinctive renewable generation profiles but also legislative constraints and respective pricing schemas for each island independently. In this way, the report yields case-specific results tailored for each island individually through the appropriate
modifications of general-purpose build simulation software.
Simulations and analysis are provided for three different types of scenarios: High-level planning case studies for demo islands and follower islands (long-term analysis for whole geographical islands) and Demo site planning studies where a smaller subset of houses and buildings from demo islands are used as a representative example of the entire island and are analysed with hypothetical configurations with
renewable technologies and storage in long-term simulations. These demo site simulations provide a basis for the equipment deployment phase of the project that is to come later on in which predefined renewable generation and storage capacities will be installed on demo islands and used in conjunction with optimization and advanced load control mechanisms in order to provide a replicable basis for selfsustainability.
