“…Data sets cover the year 2012 in a time resolution of 30 minutes. The local trade assumes losses of 7.6% through the local network (see Larruskain et al 2006). The models are run for the first nine months of the year 2012, due to the constrained accessibility of matching demand and spot price data sets.…”

Local electricity market designs for peer-to-peer trading: The role of battery flexibility

Deployment of distributed generation technologies, especially solar photovoltaic, have turned regular consumers into active contributors to the local supply of electricity. This development along with the digitalisation of power distribution grids (smart grids) is setting the scene to a new paradigm: peer-to-peer electricity trading. The design of the features and rules on how to sell or buy electricity locally, however, is in its early stages for microgrids or small communities. Market design research focuses predominantly on established electricity markets and not so much on incentivising local trading. This is partially because concepts of local markets carry distinct features: the diversity and characteristics of distributed generation, the specific rules for local electricity prices, and the role of digitalisation tools to facilitate peer-to-peer trade (e.g. Blockchain). As different local or peer-to-peer energy trading schemes have emerged recently, this paper proposes two market designs centred on the role of electricity storage. That is, we focus on the following questions: What is the value of prosumer batteries in P2P trade?; What market features do battery system configurations need?; and What electricity market design will open the economical potential of end-user batteries? To address these questions, we implement an optimisation model to represent the peer-to-peer interactions in the presence of storage for a small community in London, United Kingdom. We investigate the contribution of batteries located at the customer level versus a central battery shared by the community. Results show that the combined features of trade and flexibility from storage produce savings of up to 31% for the end-users. More than half of the savings comes from cooperation and trading in the community, while the rest is due to battery's flexibility in balancing supply-demand operations.

“…"Due to the problems associated with constructing new overhead lines, it is important to examine the possible options for increasing the transmission capacity on present sites and making maximum use of existing transmission systems through upgrades. When feasible, upgrades are an attractive alternative, because the costs and lead times are less than those for constructing new lines" (Larruskain et al 2007).…”

“…In many cases, the transmission lines' transmission capacity is limited by certain elements, e.g., switchgear elements (Larruskain et al 2007), jumpers, and certain line sections. Replacing or upgrading those elements helps improve overall transmission capacity.…”

“…However, in spite of the above-mentioned advantages, the use of HTLS conductors is still expensive, the price of which is more (in some cases much higher) than in the case of conventional ACSR. Therefore, this fact is very important especially in the market conditions and it leads to higher capital costs using the HTLS conductor types [7] - [9].…”

A stochastic approach is proposed for selecting the overhead line cross-sections that would be optimal taking into account the electricity market conditions. For this purpose, several conductor types with different conductor cross-sections were considered including the High Temperature Low Sag conductor types such as ACCC and ACCR, which are a part of the advanced technology. The total capital costs depending on the technical aspects were estimated as well. The paper proposes a method that minimizes the average value of the annual costs for the construction of a line based on a statistical representation of the electric power prices, the ambient temperature and the electrical current loads in the electrical networks. The use of the Monte-Carlo method and the mentioned statistical data allow the synthesis of a user-friendly algorithm to solve this problem. As an example of the stochastic approach, the 330 kV transmission line was selected. The solution tasks are done in the MATLAB and "SAPR LEP" software.
