“…The Distribution feeder circuits usually consist of overhead and underground circuits in a mix of branching laterals from the station to the various customers. The circuit is designed around various requirements such as required peak load, voltage, distance to customers, and other local conditions such as terrain, visual regulations, or customer requirements [2]. The various branching laterals of a distribution system are usually in a radial configuration so that energy's propagation is in one direction from the source to the load.…”

Electrical energy systems are undergoing a radical transformation in structure and functionality in a quest to increase efficiency and reliability. Due to these changes power systems became larger and larger, transmission lines crisscrossed the land forming large interconnected network. It becomes very important and necessary to operate a distribution system at its maximum capacity. For these reasons distribution system has to be modeled accurately so that analysis techniques for steady state and short circuit conditions can be developed [1]. In this work, a contribution for a modeling of a three phased unbalanced radial distribution system components, is given. A decoupled approach has been adopted so that each phase can be studied independently of the others. Some important components of a simple radial feeder has been described such as the line segment, the voltage regulator, and different models of loads have been presented and discussed. And the model has been tested for an IEEE 69 bus radial distribution system.

“…Increased field trials and robust numerical modelling should be the next step to gain investment confidence and allow BESS to reach their potential.Energies 2019, 12, 3954 For this reason and due to economies of scale, the structure of the network was designed to have large centralised generators on one end of the network, enough aggregated loads on the other end, and a system of transmission and distribution of electricity in between, with higher voltages for long distances, and lower voltages closer to the loads for shorter sections of the grid. Therefore, the electricity generation fleet could be designed optimally and perform efficiently, as short term variations are small and predictable, relative to the overall production [8].In case of non-optimised and unsupervised penetration of renewable sources, problems such as mismatch between production and demand, voltage rise, or reverse power flows at transformers [8] are more likely to arise.

“…This kind of approach represents a huge investment [15]. Installing and operating storage instead could ensure lower variations between peaks and average values, thus leading to infrastructures with lower ratings-hence, cheaper to upgrade-and more optimally used, therefore ageing more slowly [16,17].Energies 2019, 12, x FOR PEER REVIEW 3 of 32In case of non-optimised and unsupervised penetration of renewable sources, problems such as mismatch between production and demand, voltage rise, or reverse power flows at transformers [8] are more likely to arise.

The Role of Domestic Integrated Battery Energy Storage Systems for Electricity Network Performance Enhancement

et al. 2019

Low carbon technologies are necessary to address global warming issues through electricity decabonisation, but their large-scale integration challenges the stability and security of electricity supply. Energy storage can support this transition by bringing flexibility to the grid but since it represents high capital investments, the right choices must be made in terms of the technology and the location point in the network. Most of the potential for storage is achieved when connected further from the load, and Battery Energy Storage Systems (BESS) are a strong candidate for behind-the-meter integration. This work reviews and evaluates the state-of-the-art development of BESS, analysing the benefits and barriers to a wider range of applications in the domestic sector. Existing modelling tools that are key for a better assessment of the impacts of BESS to the grid are also reviewed. It is shown that the technology exists and has potential for including Electric Vehicle battery reuse, however it is still mostly applied to optimise domestic photovoltaic electricity utilisation. The barriers to a wider integration are financial, economic, technical, as well as market and regulation. Increased field trials and robust numerical modelling should be the next step to gain investment confidence and allow BESS to reach their potential.Energies 2019, 12, 3954 For this reason and due to economies of scale, the structure of the network was designed to have large centralised generators on one end of the network, enough aggregated loads on the other end, and a system of transmission and distribution of electricity in between, with higher voltages for long distances, and lower voltages closer to the loads for shorter sections of the grid.

The electrification of heat and transport sectors at different scales presents a potential for reducing Energies 2019, 12, 3954 3 of 27 GHG emissions as they are currently responsible for a substantial amount of pollutant emission [10], and draw the vast majority of their energy from the combustion of gas, oil and other fossil fuels [11]. However, shifting a significant part of the heat and transport demand to the electricity network is extremely challenging. The amount of energy it represents would generate a substantial stress on a network, which was not originally designed for it. Figure 2 gives an order of magnitude of the co...

In this work, we focus on one particular area of the smart grid, namely, the challenges faced by distribution network operators in securing the balance between supply and demand in the intraday market, as a growing number of load-controllable devices and small-scale, intermittent generators coming from renewables are expected to pervade the system. We introduce a multiagent design to facilitate coordinating the various actors in the grid. The underpinning of our approach consists of an online cooperation scheme, ECOOP, where agents learn a prediction model regarding potential coalition partners and so can respond in an agile manner to situations that are occurring in the grid, by means of negotiating and formulating speculative solutions, with respect to the estimated behavior of the system. We provide a computational characterization for our solution in terms of complexity, as well as an empirical analysis against real consumption data sets, based on the macro-model of the Australian energy market, showing a performance improvement of about 17%.
