“…In both of these approaches, the 69‐bus network is used. In [38], the connected UPQC, in which both the inverters are connected to a common DC‐link WB and PV array, is placed in distribution network for energy loss reduction. However, in [39], a combined approach for DSTATCOM allocation and reconfiguration for power loss minimisation is provided.…”

“…Thus, the direct performance comparison of the proposed approach with these approaches would be impractical. However, to have a comparative study with similar approaches, an approach for UPQC (connected topology) allocation [38] and an approach for distribution static compensator (DSTATCOM) allocation [39] are chosen. In both of these approaches, the 69‐bus network is used.…”

The study presents the modelling and allocation strategy for open unified power quality conditioner (UPQC-O) integrated photovoltaic (PV) generation system in radial distribution networks to improve the energy efficiency and PQ. An UPQC is a custom power device, which consists of series and shunt inverters. In UPQC-O, these inverters are placed in different locations in a network. There is a communication channel to share the information among these inverters to select the respective set point. Two models proposed are: (i) UPQC-O with battery and PV array (UPQC-O-WB) and (ii) UPQC-O with only PV array (UPQC-O-WOB). In UPQC-O-WB, the energy generated by PV array is stored during its operation hour to utilise it during peak hour. However, in UPQC-O-WOB, the energy generated by PV array is directly injected to the network. The proposed models are incorporated in the forward-backward sweep load flow to determine the operational parameters such as bus voltage. An optimisation problem is formulated to determine the optimal placement of UPQC-O with PV array in distribution networks. The objective function includes the investment and operational costs of inverters, battery and PV array, and the cost of energy loss. The particle swarm optimisation is used as the solution strategy.

“…The purpose of microgrid planning is to determine the size, number, combination, and in some cases, optimal location of assets that minimize the costs of investing and operating microgrids [14]. However, in community-based microgrids, it is also projected to involve factors such as the sufficiency of income for the community, the efficient allocation of resources among stakeholders, and particularly in urban communities, the improvement of the reliability levels for the users [10].…”

The reliability of the power grid is a constant problem faced by those who operate, plan and study power systems. An alternative approach to this problem, and others related to the integration of renewable energy sources, is the microgrid. This research seeks to quantify the potential benefits of urban community microgrids, based on the development of planning models with deterministic and stochastic optimization approaches. The models ensure that supply meets demand whilst assuring the minimum cost of investment and operation. To verify their effectiveness, the planning of hundreds of microgrids was set in the city of Santiago de Chile. The most important results highlight the value of community association, such as: a reduction in investment cost of up to 35%, when community microgrids are planned with a desired level of reliability, compared to single residential household microgrids. This reduction is due to the diversity of energy consumption, which can represent around 20%, on average, of cost reduction, and to the Economies of Scale (EoS) present in the aggregation microgrid asset capacity, which can represent close to 15% of the additional reduction in investment costs. The stochastic planning approach also ensures that a community can prepare for different fault scenarios in the power grid. Furthermore, it was found that for approximately 90% of the planned microgrids with reliability requirements, the deterministic solution for the worst three fault scenarios is equivalent to the solution of the stochastic planning problem.

“…During the last few years, power system researchers around the globe have been significantly contributing to the shift from passive distribution systems to active ones. However, due to the conflicting nature of the objectives to be simultaneously optimized, research is still lagging behind to design economical, reliable and yet, cyber-resilient ADSs of the future Lakshmi and Ganguly (2018). Therefore, throughout this section, we provide an overview of the main security goals and attacks on ADSs.…”

With the proliferation of smart devices and revolutions in communications, electrical distribution systems are gradually shifting from passive, manually-operated and inflexible ones, to a massively interconnected cyber-physical smart grid to address the energy challenges of the future. However, the integration of several cutting-edge technologies has introduced several security and privacy vulnerabilities due to the large-scale complexity and resource limitations of deployments. Recent research trends have shown that False Data Injection (FDI) attacks are becoming one of the most malicious cyber threats within the entire smart grid paradigm. Therefore, this paper presents a comprehensive survey of the recent advances in FDI attacks within active distribution systems and proposes a taxonomy to classify the FDI threats with respect to smart grid targets. The related studies are contrasted and summarized in terms of the attack methodologies and implications on the electrical power distribution networks. Finally, we identify some research gaps and recommend a number of future research directions to guide and motivate prospective researchers.⋆ This document is the results of the research project funded by the Centre for
