The idea of non-restricted use of LV networks by electricity consumers, producers, and prosumers

Abstract

Until now, electricity users are being connected to the LV networks by a physical electricity consumption point. In this point an electricity meter is assigned to each and every one user. A given user may use the flowing electricity only by the meter assigned to him at the consumer-specific point. This is a significant limitation in the non- restricted access to the power network. The Authors come with an idea to eliminate this restriction. The paper presents the concept of virtualization of a physical point of electric power consumption in a LV network. The proposed novel idea of using the power network will ensure the expected non-restricted access to any point of the power network for users. This seems particularly important nowadays and is dictated by the growing expectations of users’ mobility. The presented concept is dedicated especially to networks in the form of clusters (cooperatives) or energy clouds. Its application in LV networks will significantly simplify the users’ use of the power infrastructure, also in the aspect of financial settlements. This should also contribute to the rapid significant development of electro- mobility.

A Quadratically Constrained Optimization Problem for Determining the Optimal Nominal Power of a PV System in Net-Metering Model: A Case Study for Croatia

“…According to [2], the integration of a significant amount of variable renewables into the power grid requires certain actions to increase the flexibility of the existing grid: (a) electricity flow has to be allowed, not only from centralized power plants to users but also from micro-prosumers to the grid, which is aimed to ensure grid stability when installing distributed generation; (b) smart grid and demand management models aimed at increasing the flexibility and responsiveness and reducing peak-loads to deal with increased variability have to be established; (c) improving grid interconnection at the regional and international level aimed at increasing balancing capabilities, flexibility, stability, and security of supply is a must; (d) introducing energy storage capacity to store electricity (energy) from variable renewables generation when production exceeds demand. In [4] the concept of virtual point of connection (VPC) is introduced to eliminate the restriction for accessing the power grid by the current physical point of connection (PPC). Namely, the authors state that the idea of non-restricted use of low voltage (LV) networks by electricity consumers and prosumers should enable the significant development of electromobility as well as have a positive impact on future expansion of distributed energy sources (RES) in prosumer micro-installations.…”

“…Namely, the authors state that the idea of non-restricted use of low voltage (LV) networks by electricity consumers and prosumers should enable the significant development of electromobility as well as have a positive impact on future expansion of distributed energy sources (RES) in prosumer micro-installations. The concept of VPC is especially suitable for LV networks in the form of clusters or energy clouds, where the participants should experience the ease of use of the network in mentioned structures, as stated in [4]. The increase of prosumer microinstallations can also be one of the solutions for tackling the current problem of greenhouse gas emissions [5].…”

“…As a result, it is consumers who pay the highest price for green electricity [11]. There are more and more proposals on the market aimed at better management of energy and lowering its prices-especially the one from renewable sources, these include, among others, initiatives such as the creation of energy cooperatives on the capacity market, which would use the potential of renewable energy sources in rural areas [12], the idea of unlimited use of the low voltage grid by electricity consumers, producers prosumers [13], energy storage systems from renewable energy sources [14,15] or even properly designed subsidy support systems for RES [16]. At the same time, solar (as well as wind) technologies are largely favored among other technologies that use renewable energy sources, which significantly affects the development of installations supplied from these sources [17,18].…”

“…taking into account local social expectations. Without a doubt, this idea will contribute among others to popularize energy communities (ECs), including energy cooperatives and energy clusters [12][13][14][15]. According to the idea of EC, their participants in the first place strive to meet their needs using locally available resources.…”
