Welcome to the Assume Project

Agent-Based Electricity Markets Simulation Toolbox


The transformation of electricity markets associated with the transition towards high shares of renewable power generation results in the constant development of market mechanisms, increasing sector coupling, and creating new market platforms. Introducing a new market or changing the current market design does, however, affect all other markets and their participants because of their strong interrelation in not necessarily foreseeable ways, as the last changes in the German reserve markets demonstrated. This raises the need for tools and simulation models to investigate and understand such complex interplay of markets and predict possible adverse effects and misuse of market power.

With ASSUME a team of researchers aims to develop a highly modular and easy-to-use energy market simulation toolbox with integrated reinforcement learning methods. Different reinforcement learning algorithms in multi-agent simulations of electricity markets were already tested and have created promising results. This toolbox will enable an agile analysis of market designs and bidding strategies of new actors and emerging market dynamics in our fast changing energy system.

The Software Package

The ASSUME project aims to develop an open-source, agent-based simulation toolbox for electricity markets using deep reinforcement learning (DRL) algorithms.
We are very happy about and constructive feedback and contributions to the Git-repositories.

What?At what stage?Description
Markets modularityStage 1
Parent classes providing basic structure, functionality, and syntax, that are adapted by specific markets to allow interchangeability, start with a combination of IDM and DAM
Market couplingStage 1
Spatially interconnected electricity markets (NTC) and different commodity markets (gas, hydrogen)
Interchangeable market clearing algorithmsStage 1
Clearing is treated as one specific interchangeable part that can be adapted easily in each market representation
Redispatch MarketStage 2 Market after the day-ahead electricity market that handles redispatch considering the grid constraints
Sector couplingplannedHow to model sector coupling technologies in detail
Assets modularityStage 1
Parent classes providing basic structure, functionality, and syntax, that are adapted by specific agents to allow interchangeability
Learning agentsStage 1
Usage of Deep Reinforcement Learning for the definition of bidding policies 
Exchangeable bidding policiesStage 1
Naive policies and policies that are learned by the RL agents
Flexible Demand Stage 2In Stage 1, fixed demand is used, and later we integrate different demand-side agents that have an individual collection of technologies themselves, such as heat pumps and PV
Different bid typesStage 2Incorporation of different bids such as block bids, etc.
Portfolio OptimizationplannedOption is accounted for in architecture; the actual implementation to be discussed
NetworkStage 1
Adaptable network representation that is also able to read and solve PyPSA examples in Assume
Communication layerStage 1
e.g. Order-books used between agents and markets, there we rely on mango agents
Interoperable IO formatsStage 1
Standard data formats adapted from other open source tools and general conventions, enables scenario reading from Amiris and PyPSA
Scalability and parallel executionStage 2Enabels running Assume in different Docker containers
Deep Reinforcement Learning
Strategies for multiple unit typesStage 1Including power plants and different storages
Strategy for Multi Market BiddingplannedTo handle the variety of configurable markets, we must adjust the DRL algorithmic settings to manage multiple markets at once.
Eplainability featuresplannedAs the developed strategy of DRL follows an rather explorative nature, we need to develope ways of assessing the learned startegies with the help of explainable RL.
Different AlgorithmsplannedImplementing a PPO in addtioin to the MATD3, incorperating LSTM plocies and importance sampling buffers for the MATD3
