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
Sector couplingplannedHow to have more sector coupling technologies
Different Market representation (separate DA and ID) plannedHow electricity markets are modeled, at the first stage only merge of DA and ID, which might be redefined later on
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 plannedIn stage 1, fixed demand and no bidding for the demand side yet, this will be adapted
Portfolio OptimizationplannedOption is accounted for in architecture, the actual implementation to be discussed
Different bid typesplanned Incorporation of different bids such as block bids etc.
NetworkStage 1
The idea is to represent the markets as a network using graph theory, this network does not represent the power grid, rather defines relations and the degree of relations to other agents/components
Communication layerStage 1
E.g. Order-books, or mango agents tbd
Interoperable IO formatsStage 1
Standard data formats adapted from other open source tools and general conventions
Scalability and parallel executionplannedMight be solved with predefined packages like Mango agents or repast4py, tbd
