Refactoring Energy Systems

Lead Research Organisation: University of Bristol
Department Name: Computer Science

Abstract

The complexity of the present UK energy system (including numerous generators ranging from nuclear plants to individual households, transmitters, distributors, storage providers, regulators, and consumers) is ever growing.

While once only a few major power producers delivered energy to the whole country, today the energy system is drastically changing. To give a few examples: every household can supply energy into the grid, the environmentally-concerned consumers wish to purchase energy from specific sources, and communities and businesses may wish to ascertain energy self-sufficiency, but also expect to rely on the main grid as provider of the last resource. Transmission capacity must grow to meet increased consumption needs. Intermittence of new energy types (e.g., wind and solar), require larger and longer-term storage.

As the technical and participant variety in the energy system grows, the system's architecture can no longer remain uniform, for instance, some communities could rely on wind energy, others on biofuels; the level of participation of smaller suppliers would vary per locality, as will priorities of communities. Thus, there is no longer one optimal energy system architecture for the whole country. Instead, each community should be able to identify the best way that its energy system could be structured and take planned steps towards achieving and maintaining this optimal structure.

Thus, this fellowship aims to transform how the energy system is viewed, managed and evolved: moving away from the current perception of a single, uniform system across the whole of the UK, to that of localised, adaptive, largely self-reliant system-of-systems. In this new setting, the local systems will each be individually optimised, yet globally connected.

To enable this locally optimised and globally connected energy system, the fellowship will deliver a set of system refactoring patterns, tools, and techniques.
Refactoring is a disciplined approach to gradually changing the internal structure of an existing system without changing its externally useful services.

The fellowship will:
1. Collect and integrate data sources and models that would allow each community to monitor the current state of their local energy system, identify emerging problems, and address these problems through refactoring patterns. The models will also help to observe the expected effects of a refactoring application both locally and on the larger, interconnected system-of-systems.

2. Set up an open, commonly accessible technical infrastructure for data recording and model evaluation. A simple (non-specialist focused) user interface will be set up to enable all interested stakeholders to choose, evaluate and interpret models.

3. Deliver innovative methods, tools, a pattern catalogue, and good practice guidelines for energy systems refactoring.

4. Engage individuals, communities, businesses, regulators, and NGOs with the localised, renewables-based energy generation activities.

Planned Impact

The fellowship will deliver impact to core energy system stakeholders (such as, for instance, generation and transmission systems organisations, and regulators), researchers, and the wider community through the refactoring patterns and methods, open data and model evaluation infrastructure, and stakeholder engagement activities.

Through the systems refactoring patterns and methods, the energy system stakeholders will be able to:

1. Identify areas in energy systems where refactoring is required, pinpointing problematic issues before they aggravate and further deteriorate the system's efficiency;

2. Evaluate possible refactoring patterns and strategies, gauging the impact of alternatives and basing their choices on the results of a number of model evaluations;

3. Reduce complexity of the energy system, making these systems more adaptive to the changing needs of the users, technology, and the environment.


Through the open infrastructure data and models:

1. The energy system stakeholders will be able to evaluate impact of possible change decisions at community, local, and global levels. This will allow for considered decision-making, with reduced risk of unexpected consequences.

2. The wider community members (e.g., individuals who consider installation of personal generation equipment, or groups that wish to find best ways of trading their generated energy, etc.) will be able to assess alternative options and decide upon the most preferred solution for themselves, using end-user friendly query and model evaluation interfaces.

3. Researchers from across the UK (as well as the world) will derive new hypothesis, models and theories, as well as validate their research against the free, large datasets.

4. Businesses will also be able to derive new products and business models based on free data and modelling/evaluation framework.


Through the stakeholder engagement activities:

1. Closer collaboration and partnership will be established between the various parities (from regulators to major power generators and community groups) and at various levels (from government to individual household-level prosumers) of the energy systems;

2. Direct feedback to proposed changes to the energy systems and policies will be enabled, reducing uncertainty of the decision consequences, as well as saving time and money on trials and pilots;

3. Traceability of the decisions and actions will establish clear accountability record for specific decisions to individuals and/or organisations, making energy systems decision-making transparent.

Description So far, the work on the Refactoring Energy System project has focused on the role of Software/Requirements Engineering in supporting sustainable systems (of which energy systems are one example); on energy trading and consumption themes; and on use of distributed ledgers as enables for energy trading.
The summary of the key findings so far:

1. Role of Requirements Engineering in fostering sustainable systems: our research has identified requirements engineering as the key point at which sustainability concerns can be integrated into software systems. Such sustainability-enabled systems could then proceed to improve/change the society or communities within which they are located, by, for instance, inducing reduction of energy consumption and waste, supporting funding for installation of cleaner energy sources, etc. Initial requirements patterns, e.g., for enabling equity and equality through software have also been identified.

2. Energy consumption is studied through the lens of Demand-Side Response activities. A wide variety of research and trial studies have been conducted on this topic. Yet, so far there had been no requirements elicitation exercise undertaken to explicitly state the requirements that DSR automation service must address to be accepted by the households at large. Our work has carried out just such an exercise by undertaking interviews with 30 household representatives. From these we have identified a number of key groups of requirements, such as the need to retain ultimate appliance control (e.g., through manual overrides); need for discriminating between specific appliances and their contexts for automation; and the need to be able to associate personal meaning to the service participation process by setting own goals.
Along with DSR requirements elicitation study, a novel requirements elicitation technique, based on the Grounded Theory Analysis, is being developed.

3. Energy trading is studied as an activity that takes place over a dedicated software platform. Here an energy trading platform for households and small businesses, based on DAG-based block-free distributed ledgers is studied. Such a platform aims to overcome transaction processing latency and high fees induced by the mining and block-size constraints of the blockchain solutions. We conclude that the block-free DAG-based ledgers are suitable for peer-to-peer energy trading, yet they must adhere to specific design constraints imposed by the nature of the energy domain. For insistence, since energy is generated and used for each discrete time period, the ledger must ensure transactions for period t are concluded before those for (t+1) commence. This requires introduction into the DAG of dedicated interval-end termination nodes.
Exploitation Route Research on the role of software and requirements engineering is directly relevant to the software community of practice, as well as to the regulators and standardisation bodies who may define new standards of practice aimed at fostering sustainability through software.

Findings from the Demand-Side Response studies will result directly in software product development to enable automated DSR service delivery, leading to new business opportunities, as well as improved energy systems' asset utilisation. Similar impact could be expected form the better understanding of use and constraints of distributed ledgers for energy trading.

Title Requirements elicitation through review of grounded theory 
Description When undertaking requirements elicitation some relevant question (e.g., how to improve adoption of the intended system) cannot always be addressed through the established means of direct need and want elicitation. We provide a method for eliciting such requirements through use of grounded theory analysis. The theory emerging from such analysis produces a set of additional requirements which cannot be directly elicited from individuals/groups, and would otherwise be missed out. Thus, this method uses the theory generated through grounded theory analysis as an additional valuable source of software system requirements.
