Exploiting Symmetry in the Generation Expansion Planning Problem to Accelerate Crossover: Determining European Energy Investment Strategies Faster

Computational efficiency is essential for large-scale mathematical optimisation problems, such as the generation expansion planning problem, to be practically applicable. In linear programming solvers, crossover is frequently a bottleneck when solving optimisation problems. This study aims at determining why crossover is a bottleneck in solving...

Secure expansion of energy storage and transmission lines considering bundling option under renewable penetration

This paper presents a multi-stage expansion model for the co-planning of transmission lines, battery energy storage (ES), and wind power plants (WPP). High penetration of renewable energy sources (RES) is integrated into the proposed model concerning renewable portfolio standard (RPS) policy goals. The possibility of bundling existing...

Capturing Chronology and Extreme Values of Representative Days for Planning of Transmission Lines and Long-Term Energy Storage Systems

The growing penetration of renewable energy sources (RESs) is inevitable to reach net zero emissions. In this regard, optimal planning and operation of power systems are becoming more critical due to the need for modeling the short-term variability of RES output power and load demand. Considering hourly time steps of one or more years to model...

The Amsterdam Extension Plan: Greenery organising the city

The widely known General Extension Plan of Amsterdam (Algemeen Uitbreidingsplan van Amsterdam (AUP)) from 1935, with Cornelis van Eesteren as its head architect, is one of the most famous schemes of this kind even today. It is known for its unique and sophisticated system of the urban greenery which can be reached within a 10 minutes radius from...

Uncertainty in Long-Term Grid Planning: Approaching Transmission Expansion Planning through the Framework of Decision Making under Deep Uncertainty

Motivations for sustainability are initiating an energy transition that is changing the European energy domain. The transition effectuated the adaptation of large volumes of wind and solar based generation capacity. The intermittent power-output of these Variable Renewable Energy Sources challenges the balancing operation of the electricity...

Efficient reduction techniques for a large-scale Transmission Expansion Planning problem

The aim of Transmission Expansion Planning (TEP) studies is to decide which, where, and when new grid elements should be built in order to minimize the total system cost. The lumpiness of the investment decisions, together with the large size of the problem, make the problem very hard to solve. Consequently, methods should be put in place to...

The integrated offshore grid in Europe: Exploring challenges for regional energy governance

The deployment of offshore wind and power transmission in the European North Sea is accelerating. Stakeholders advocate regional governance for the European grid expansion, which may evolve into a pan-European governance and is key to developing integrated, hybrid offshore projects. However, such projects are still scarce. We thus analyze the...

Expansion Governance of the Integrated North Seas Offshore Grid

The expansion of offshore power transmission and generation in the North Seas of Europe is accelerating rapidly. This is due to several drivers, including the decarbonization and reform of the European power system, and innovations in offshore wind and high-voltage direct current transmission. So far, this European North Seas offshore grid is...

Design and Application of Scalable Evolutionary Algorithms in Electricity Distribution Network Expansion Planning

In our modern daily life, many activities require electricity, for example, the usage of domestic appliances, manufacturing, communication, and transportation. It is therefore essential to maintain a reliable supply of electricity to ensure the operation of such activities. The electricity supply, in a large part, depends on the underlying...

Expansion planning of the North Sea offshore grid: Simulation of integrated governance constraints

The development of offshore transmission and wind power generation in the North Sea of Europe is advancing fast, but there are significant barriers to an integrated offshore grid in the region. This offshore grid is a multi-level, multi-actor system requiring a governance decision-making approach, but there is currently no proven governance...

Transmission expansion simulation for the European Northern Seas offshore grid

HVDC innovations and the integration of power markets and renewables drive the development of a European Northern Seas offshore grid. This power transmission system performs two functions: interconnecting Northern European onshore power systems, and connecting offshore wind farms. Despite its benefits, the development of an integrated...

Identifying options for the multi-terminal expansion of the COBRAcable

A meshed North Sea offshore electricity grid with high renewable energy penetration, as envisioned by the European Commission, is still at its infancy. Currently, point-to-point high-voltage DC interconnections across borders are already being implemented successfully, but the next steps of expanding these interconnectors with additional...
