“…This power depends on many factors, such as orientation of photovoltaic cells, time of day and month, and environmental conditions. The Beta probability density function has been used to model the radiation probabilities of the sun, and the output power of the photovoltaic cells can be calculated by the following equation

P_{PV} ((), R) = ({, \begin{array}{l} P_{normalr, PV} \frac{R^{2}}{R_{STD} R_{C}} & 0 \leq R \leq R_{C} \\ P_{normalr, PV} \frac{R}{R_{STD}} & R_{C} \leq R \leq R_{STD} \\ P_{normalr, PV} & R_{STD} \leq R_{C} \end{array}) .

In this work, the impact of power exchange on reliability and economic indices of networked microgrids (MGs) is investigated. To this end, new reliability and economic indices are defined. The indices for emergencies in islanded and grid connected modes are evaluated. To increase the accuracy of simulation, a new evaluation method having a unique and precise answer is introduced. To optimize the customer interruption cost (CIC) reduction, the power exchange algorithm based on CIC reduction is presented. In this algorithm, the power exchange between MGs is carried out according to the cost of electricity and the value of the interrupted load. For this purpose, different scenarios of electricity prices are considered. To prove the efficiency of the proposed methods, these methods are tested on the well‐known distribution system bus 2 RBTS. Results reveal that the power exchange between MGs or MGs with grid can considerably affect the reliability and economic indices of MGs.

“…So that a new pattern that can be referred as multi-MGs has emerged in ADS, shown as Figure 14. In this architecture, the goal of global coordination in ADS and regional autonomy in MGs can be achieved [118][119][120]. At present, ADSs with multi-MGs have been studied in some literature.…”

“…At present, ADSs with multi-MGs have been studied in some literature. However, most existing literature are directed towards the operation issues but not planning problems [118][119][120][121][122]. Even though there has been a small part of literature that spends efforts on the planning of ADS with multiMGs, there are many problems that remain unsolved [117,123].…”

Due to the widespread deployment of distributed energy resources (DERs) and the liberalization of electricity market, traditional distribution networks are undergoing a transition to active distribution systems (ADSs), and the traditional deterministic planning methods have become unsuitable under the high penetration of DERs. Aiming to develop appropriate models and methodologies for the planning of ADSs, the key features of ADS planning problem are analyzed from the different perspectives, such as the allocation of DGs and ESS, coupling of operation and planning, and high-level uncertainties. Based on these analyses, this comprehensive literature review summarizes the latest research and development associated with ADS planning. The planning models and methods proposed in these research works are analyzed and categorized from different perspectives including objectives, decision variables, constraint conditions, and solving algorithms. The key theoretical issues and challenges of ADS planning are extracted and discussed. Meanwhile, emphasis is also given to the suitable suggestions to deal with these abovementioned issues based on the available literature and comparisons between them. Finally, several important research prospects are recommended for further research in ADS planning field, such as planning with multiple micro-grids (MGs), collaborative planning between ADSs and information communication system (ICS), and planning from different perspectives of multi-stakeholders.

“…In relation to that, renewable DG technologies may lead to various challenges in system stability, mainly low voltage stability resulting from low support for power sharing, decrease in angular stability due to overall lower system inertia (in photovoltaics), low frequency power oscillations and inability to serve as reserve for the power system. SDN under the SG paradigm has expected to ensure reasonable power quality and power system stability, during transients and high DG penetration [8,57,58].…”

Smart Distribution Networks: A Review of Modern Distribution Concepts from a Planning Perspective

et al. 2017

Smart grids (SGs), as an emerging grid modernization concept, is spreading across diverse research areas for revolutionizing power systems. SGs realize new key concepts with intelligent technologies, maximizing achieved objectives and addressing critical issues that are limited in conventional grids. The SG modernization is more noticeable at the distribution grid level. Thus, the transformation of the traditional distribution network (DN) into an intelligent one, is a vital dimension of SG research. Since future DNs are expected to be interconnected in nature and operation, hence traditional planning methods and tools may no longer be applicable. In this paper, the smart distribution network (SDN) concept under the SG paradigm, has presented and reviewed from the planning perspective. Also, developments in the SDN planning process have been surveyed on the basis of SG package (SGP). The package presents a SDN planning foundation via major SG-enabling technologies (SGTF), anticipated functionalities (SGAF), new consumption models (MDC) as potential SDN candidates, associated policies and pilot projects and multi-objective planning (MOP) as a real-world optimization problem. In addition, the need for an aggregated SDN planning model has also been highlighted. The paper discusses recent notable related works, implementation activities, various issues/challenges and potential future research directions; all aiming at SDN planning.
