Grid-connected rooftop and ground-mounted solar photovoltaics (PV) systems have gained attraction globally in recent years due to (a) reduced PV module prices, (b) maturing inverter technology, and (c) incentives through feed-in tariff (FiT) or net metering. The large penetration of grid-connected PVs coupled with nonlinear loads and bidirectional power flows impacts grid voltage levels and total harmonic distortion (THD) at the low-voltage (LV) distribution feeder. In this presentation, LV power quality issues with significant nonlinear loads were evaluated at the point of common coupling (PCC). Various cases of PV penetration (0 to 100%) were evaluated for practical feeder data in a weak grid environment and tested at the radial modified IEEE-34 bus system to evaluate total harmonic distortion in the current (THDi) and voltage (THDv) at PCC along with the seasonal variations. Results showed lower active, reactive, and apparent power losses of 1.9, 2.6, and 3.3%, respectively, with 50% solar PV penetration in the LV network as the voltage profile of the LV network was significantly improved compared to the base case of no solar. Further, with 50% PV penetration, THDi and THDv at PCC were noted as 10.2 and 5.2%, respectively, which is within the IEEE benchmarks at LV.

The Syed Babar Ali School of Science and Engineering (SBASSE) at LUMS, initiated in 2008, is the first private research school for science and engineering in Pakistan with a vision to carry out world-class, multidisciplinary education and research. Modelled on some of the leading universities of the world, it aims to be a paradigm shift for science and engineering education in the country. The Electrical Engineering (EE) programme at SBASSE is designed to enable students to be well-prepared to contribute to the rapidly changing and expanding needs of technology. The EE curriculum provides students with a strong foundation due to an emphasis on basic sciences and the development of excellent engineering skills through carefully planned core and elective courses. EE students also learn through a combination of design and lab work. The EE curriculum covers the essential breadth and depth needed for contemporary professional practice. Four important concentration areas have been identified: Communications, Signals and Systems Electronics and Embedded Systems Devices, Optics and Electromagnetics Modern Power and Energy Systems In the final year of their undergraduate studies, students are involved in a year-long capstone project to demonstrate their practical knowledge. This handbook consists of a brief description of the final year projects for the 2021–2022 session. This effort has been coordinated by Dr. Nauman Zafar Butt, with the assistance of Mr. Usama Bin Qasim and Mr. Affan Anwar.

Advancements in smart grid technologies have resulted in increased reliability of service for consumers. Although, faults and outages resulting in blackouts are inevitable, service is restored back to normal. Service restoration is a decision making and action actuating process (either executed centrally or distributively) in which the system operator executes a set of actions to minimize the impact of an outage on customers while maintaining stability and inter-operability of the grid.

In the literature, two main methodologies have been adopted to solve the load restoration problem. One approach considers it as a classical deterministic optimization problem with an objective to maximize (critical) load pickup incorporating several constraints. The other considers it as a multi-agent system (MAS) and restores the loads based on heuristics and agent behavioural modelling. Lack of standardization has limited the scope of communication technologies in smart grids, especially in the service restoration process. However, with the increasing installations of smart switches, tie-lines and sectionizers as well the deployment of new Distributed Energy Resources (DERs) an obvious but unexplored research area is examining the role of communication layer in realizing cyber-physical distribution systems. Agents can interact socially and cooperate to exchange sensory information and actions to restore loads over a communication layer. Also, there are new opportunities to consider Synchronous Generators or Back-up Generators (BUGs) as a source of providing black-start capability to grid-tied non-dispatchable inverters. In this way, the utility of BUGs has increased to harness power from non-dispatchable inverters rather than merely providing backup to local loads. The system operating conditions do not remain constant during the restoration period. This work aims to develop a cyber-physical framework for load restoration with intentional islanding (i.e Mirco-Grid Formation) and consideration of uncertainties in demand and renewable resources.

After a major blackout, the fault areas are isolated from the upstream network, where customers in the upstream are continued to be served from the main grid. Those in the downstream can either be served from main grid (after tie-line or sectionizer switching) or through several Micro-Grids (MGs-intentional islands). The challenge involved is ascertaining the span of the MGs based on the available generation and load within the MG, whilst keeping the grid stable, harnessing power from non-dispatchable DGs, determining the effect of delays in switching actions on stability and uncertainties associated with demand and generation.
