Abstract

Great Britain has begun to implement significant modifications that are ought to change the national electricity generation. Adding a large amount of renewable capacity to the energy mix will impact different areas of energy use from the landscape used for installation to the electricity market. This study presents an approach to determine the optimal locations of renewable energy installation based on predictions of renewable expansion under consideration of grid constraints. The occurring cost are analysed with regard to the expansion cost and the impact on the wholesale electricity prices.

Highlights

Great Britain is in the process of transforming the way its energy demands are met by shifting from conventional generation by accommodating the energy system to be more suitable for low-carbon energy technologies; few steps have been made to ease this transition.The disconnection within the grid grows further as with the prospective increasing share of renewable generation in the British energy system
The MinCost simulation displays the costs resulting from running the model according to the most optimal positioning of renewable resources, it does not account for grid constraints
The paper analysed and presented the impact of increasing renewable generation throughout Great Britain for various regions, the cost that would incur with renewable installations, and the overall impact on wholesale electricity prices

Summary

Introduction

The disconnection within the grid grows further as with the prospective increasing share of renewable generation in the British energy system This is because more and more decentralised generation is connected below the transmission grid level, yet the distribution grids have not been brought up to date to the needed extent, especially given the fluctuating nature of renewables. Existing literature, such as [1], has already highlighted the impact of renewable energy sources (RES) expansion in future scenarios on the power system of Great Britain. Regionalised demand patterns are utilised, which are successively assigned to substations at the voltage level of 132 kV and below
