“…PyPSA is already used by more than a dozen research institutes and companies worldwide, 70 people are registered on the forum [27] and the website [26] has been visited by people from over 160 countries. As of October 2017 it has been used in six research papers [28], [29], [30], [31], [32], [33]. Users have already extended PyPSA for integer transmission expansion [28], [34] and in the grid planning tool open eGo [35].…”

Python for Power System Analysis (PyPSA) is a free software toolbox for simulating and optimising modern electrical power systems over multiple periods. PyPSA includes models for conventional generators with unit commitment, variable renewable generation, storage units, coupling to other energy sectors, and mixed alternating and direct current networks. It is designed to be easily extensible and to scale well with large networks and long time series. In this paper the basic functionality of PyPSA is described, including the formulation of the full power flow equations and the multi-period optimisation of operation and investment with linear power flow equations. PyPSA is positioned in the existing free software landscape as a bridge between traditional power flow analysis tools for steady-state analysis and full multi-period energy system models. The functionality is demonstrated on two open datasets of the transmission system in Germany (based on SciGRID) and Europe (based on GridKit).

“…Consequently, a meshed offshore grid in the North Sea has been proposed as an option for connecting transmission and offshore wind generation investments in the region (Konstantelos et al, 2017;Gorenstein Dedecca et al, 2017;de Decker et al, 2011). The meshed offshore grid can be optimized assuming a fixed onshore generation development (Gorenstein Dedecca et al, 2017; however, joint optimization of the onshore and offshore parts has been suggested to find the overall optimal system (Gea-Bermudez et al, 2020a;Gorenstein Dedecca and Hakvoort, 2016). This paper presents results by comparing an integrated approach, where meshed grid and onshore transmission and generation investments are optimized jointly, to a project-based scenario, where each offshore wind power plant (OWPP) is connected individually to the onshore power system.…”

North Sea region energy system towards 2050: integrated offshore grid and sector coupling drive offshore wind power installations

et al. 2020

Abstract. This paper analyses several energy system scenarios towards 2050 for the North Sea region. With a focus on offshore wind power, the impacts of meshed offshore grid and sector coupling are studied. First, a project-based scenario, where each offshore wind power plant is connected individually to the onshore power system, is compared to a meshed grid scenario. Both the amount of offshore wind power installed and the level of curtailment are assessed. Then, these results are compared to a scenario with sector coupling included. The results show that while the introduction of a meshed grid can increase the amount of offshore wind power installed towards 2050, sector coupling is expected to be a more important driver for increasing offshore wind power installations. In addition, sector coupling can significantly decrease the level of offshore wind curtailment.

“…The PLI can be viewed as the ultimate level of integration due to its relative high capacity. However, integrated grid solutions are challenging in terms of cooperation among bordering countries as discussed in, for example, Gorenstein Dedecca, Hakvoort, and Herder (). One example being the distribution of costs and benefits due to asymmetric implications of multinational projects.…”

An increasing share of variable power feed‐in is expected in the next decades in the European power system, with a particularly high offshore wind potential in the North Sea region. This demands more temporal‐ and spatial flexibility in the system, an adequate grid infrastructure can provide both. This study presents an engineering‐economic approach evaluating the impact of novel infrastructure designs towards a fully integrated North Sea offshore grid, including TenneT’s vision of a power link island (PLI). A PLI is an artificial island for transnational power exchange and distribution of offshore wind resources. We introduce the concept and evaluate the economic benefits and system implications under three different case studies incorporating 2030 scenarios from European Network of Transmission System Operators. The results demonstrate system cost savings up to 15.8% when comparing a fully integrated PLI solution with traditional, radial typologies. The PLI did in general result in more efficient system dispatch of wind resources, where the involvement from Norway, Great Britain, and Germany occurred most frequently in terms of grid reinforcements and expansions.
