Local electricity sharing schemes have the potential to play an increased role in the Australian National Electricity Market as the penetration of distributed energy resources (DERs) continues to grow. These models allow participants to share energy between separately owned and operated DERs, however are largely untested. While embedded networks ha...

Electricity cost is one of main production costs for flow shops. Providing frequency regulation services can help electric loads reduce their electricity costs. Previous studies mostly focus on automatic generation control (AGC) strategies for other types of electric loads, such as air conditioners, EVs or battery storage. In this paper, we find fl...

... Firstly, the current pace of sustainable energy policy developments in Australia is generally perceived to be lagging behind technological advances, driving communities to take their own actions to meet local sustainability goals (Bowyer, 2015). Similarly, community-owned electricity sharing schemes (which are classified as CORE initiatives) are seen as a way to move away from traditional electricity grid arrangements and attain local energy autonomy (Stringer et al., 2017). CORE initiatives may also provide a valuable and sustainable income stream to the community (Adams and Bell, 2015), since internal tariffs in Community ENs can generate monetary savings for participants compared to them remaining with market-offers. ...
... The Byron Bay Shire in Australia is in the process of implementing a 100% Renewables initiative (ITP Renewables, 2017). Stringer et al. (2017) reported on a case study of a local energy sharing scheme for a pseudo-EN (essentially a peer to peer trading arrangement) in the Byron Arts and Industrial Estate. It modelled 11 commercial customers with and without solar, and quantified the financial outcomes for the participants, the DNSP and the retailer. ...
... To fulfil the objective of this study, we propose criteria for assessing the appropriateness of EN arrangements, use a model developed in Python to simulate a Community EN with energy sharing, and under different arrangements, calculate outcomes for the for the ENO, compare financial and equity outcomes between participants with and without solar and A/C, and assess the incentives for PV deployment. An existing Python model developed for use in the study by Stringer et al. (2017) and adapted for this purpose. ...
The shift to low-emissions energy production has gained significant traction in Australia and around the world. Community Renewable Energy (CORE) projects are on the rise, reflecting the desire of communities to take control of their own energy goals, and embedded networks (ENs) are emerging as part of the CORE movement. An EN is operated by an EN operator (ENO), who can purchase electricity at the parent point and on-sell it to customers within the EN. This provides the opportunity for innovative internal electricity tariff structures to be designed that can help meet community goals such as increased local renewable energy and improved equity impacts. This study aims to understand the implications of Community EN arrangements and tariff design for the financial, environmental and social outcomes of those connected to the EN. An energy sharing EN model is used to simulate financial outcomes for participants and the ENO in a Community EN of 60 households as a function of:-EN PV penetration, and-internal retail tariff structure. It was found that with the appropriate internal settings all solar and non-solar customers could save an average of approximately $200 at all levels of PV penetration. However, arrangements with PV penetrations above approximately 50% were not viable as the ENO lost profitability since EN loads could be fully met by internal solar generation. These results indicate that there may be some conflicts between Community EN financial, renewable and equity goals. While achieving all goals simultaneously can be difficult, it is apparent that the 'Community EN with energy sharing' model is a credible option in the CORE space to help meet community goals, and careful internal design can help ensure that the desired goals are prioritised. In addition, both non-solar and solar customers are able to benefit through a scheme such as that explored here, addressing a key inequity in the energy industry.
... With the emergence of distributed energy resources (DER), the relevance of so-called "prosumers"-entities/households that are producer and consumer of energy in one-increases [1] [2]. There are different aspects in the context of energy markets and prosumers, which are researched, and which impact each other e.g. the definition of prosumer models and how they fit into the energy market; a highly regulated market framework and how it integrates new market entrants; how new technologies and their characteristics are adapted to; and the economic aspects of energy prosumers. ...
... The motivation for consumers to become prosumers in the energy sector broadly mirrors that of other markets, yet, the context of increasing energy prices and the drive towards green energy play prominent roles. The role of the prosumer is not only understood as purely producing and consuming energy but because of the generally non-storable nature of electricity, they are also active market participants [2] [33] [38] [39]. This stems from the fact that prosumers might supply to or demand electricity from the grid at random and this makes them exposed to electricity market prices and dynamics. ...
This paper analyses the economics of pooling small UK based local electricity prosumers with back-up access to the National Grid and compares it to the current conventional UK electricity supply model—business as usual (BAU) approach. This is contextualized against the UK energy market framework, prosumer research and changing energy market dynamics. For the economic assessment a three-tiered production/supply and consumption model is developed based on site specific levelized cost of electricity (LCOE) and other cost parameter to operate the model. Modeling results indicated the economic feasibility and advantage of a prosumer approach in a significant number of modeling scenarios. Additionally, a break-even analysis for the two approach-es was undertaken to understand the sensitivity of individual input parameters.
