Just released: network-secure bidding optimization of aggregators of multi-energy systems in electricity, gas, and carbon markets

Our researchers from INESC TEC have just published a new article on Elsevier. The paper “network-secure bidding optimization of aggregators of multi-energy systems in electricity, gas, and carbon markets” presents a network-secure bidding optimization strategy to assist aggregators of multi-energy systems in calculating electricity (energy and reserve), gas and carbon bids considering multi-energy network constraints.

The proposed strategy is based on the alternating direction method of multipliers. Results show that joint optimization of multi-energy systems reduces aggregators’ costs by 89% compared to a single energy-vector approach.

The full article is available here.

Mapping future power generation scenarios for Portugal, Croatia, and the UK

To support the development and performance evaluation of the ATTEST toolbox components, a set of relevant test cases have been developed in the last weeks.

Each test case consists of a series of files containing electric grid information (grid topology, generation and load data, assets data, etc.) that supports the simulation of a real (or realistic) situation, whether it is a scenario for long term planning, operation or asset management.

To build the test cases, the ATTEST team mapped the existing network and installed capacity of Portugal, Croatia and the UK in 2020. Then, researchers collected official policy documents (such as ten-year development plans for transmission and distribution, energy strategy) and projections to support high-level estimations of energy generation and consumption up to 2050.

The result is yet to be fully released, but we have published a set of infographics that resume the key data for each country. You can find them on the resources page.

Just released: Transmission Expansion Planning Model Considering Battery Energy Storage, TCSC and Lines Using AC OPF

Flexibility has become a requirement for modern power systems dominated by renewable generation sources. It can be extracted from different assets, ranging from demand response to fast generating units. This paper proposes an investment model that nds an optimal mix of transmission-level non-generation flexible assets: battery energy storage (BES), thyristor-controlled series compensators (TCSC), and transmission lines. The role of BES is to offset renewable generation in time, but its power converter is additionally utilized to provide voltage regulation by injecting/withdrawing reactive power.

TCSC is used to alter power flows and increase existing lines’ capacity, while new power lines are used to increase bulk power transfer. The proposed planning model uses a linearized AC OPF and employs Benders’ decomposition to develop an iterative procedure for obtaining the optimal solution. The presented case study illustrates the usefulness of the model for different BES costs and investment policies.

Operational agility in the energy markets

The arrival of new energy sources poses an unprecedented challenge for global power systems. As most Renewable Energy Sources (RES) strongly depend on weather conditions, future energy systems will need to deal with new generation patterns and increased flexibility needs for which they are not prepared.

ATTEST contributes to the development of energy systems by adding some new features (while improving some of the existing ones) to their planning, operation and maintenance procedures. It engages Distribution System Operators (DSOs), Transmission System Operators (TSOs), and consumers in one optimized energy cycle of reduced costs, minimum waste, and maximized efficiency.

Overall, ATTEST improvements in energy systems fall into six areas:

Increasing power system flexibility and generation back-up capacity

New mechanisms of demand-side flexibility activation compensate for the increased variability on the production side as both transmission and distribution systems will benefit from a progressive proliferation of energy storage solutions. End-user flexibility activation schemes also allow consumers to participate in system services.

Integrating different energy systems

The integration of different energy systems aims to deliver additional flexibility and avoid service disruption by primarily satisfying their needs at the demand side. Multi-Energy Systems (MES) can also switch between energy sources and large scale storage systems, thus promoting the integration of RES.

Improving the interaction between DSOs and TSOs

The coordination between DSOs and TSOs leads to the creation of new market architectures, codes, and rules – which are necessary given the integration of RES at different voltage levels. Advanced ICT solutions will also ensure the provision of ancillary services based on the available flexibility from the distribution system.

Ensuring the security of operation against critical disturbances

Transmission and distribution grid dynamics will include the careful assessment of instability phenomena to efficiently respond to the challenge posed by the integration of distributed generation with little or no inertia.

Building a user-centric energy system that empowers consumers

Innovative aggregation business models encourage consumer participation in the electricity markets. Once operational and truly competitive, energy systems fulfill consumer needs while raising their awareness about the energy system value chain.

Promoting the digitalization of the energy sector

ICT will provide unprecedented access to information on energy usage and control to all players in the energy market. Such an environment improves efficiency, reduces costs, and fosters the integration of renewables, thus unlocking the real potential of Distributed Energy Resources (DER).

We are building the energy systems of the future with efficiency in mind. Follow us to be the first to know about our project demos and results!
