There is a growing interest in 'smart grid' technologies in both industry and academic circles. Few attempts have been made to develop a written specification consummated with standards agreed upon by members of both coteries, due to lack of government support. Utilities in the state of California are obligated, by state legislature, to create a more: efficient, reliable, and intelligent electric power system. This initiative along with Florida Power & Lighting's 'Smart Grid' pilot program has created a sense of exigency within the industry regarding smart grid technologies and standardizations. Their accomplishments are beginning to shape the policies and standards with marginal input from academic societies, ushering in a very lopsided, and business acclimatized set of standards. We will present and analyze, a SCE 'Smart Grid' use case, in which the utilities back office applications interact with the customer's meter, and provide technical recommendations for system security improvements.

The optimization of power distribution networks is a critical challenge in the evolving energy sector, where increasing demand, aging infrastructure, and the integration of distributed energy resources necessitate smarter, more resilient systems. Smart grid technology offers a transformative framework by combining advanced sensing, two-way communication, and intelligent control mechanisms to enhance the efficiency, reliability, and flexibility of power distribution. This paper presents an optimization-oriented approach to modernizing distribution networks, focusing on adaptive reconfiguration, demand response, loss minimization, and voltage stability. Techniques such as real-time monitoring, predictive analytics, and automated feeder reconfiguration are explored to reduce technical losses and improve power quality. The proposed framework leverages optimization algorithms, including mixed-integer linear programming (MILP) and heuristic-based methods, to balance supply and demand, accommodate renewable integration, and ensure cost-effective operation. Simulation results demonstrate significant improvements in network performance, including reduced outage durations, enhanced load balancing, and operational cost savings. Additionally, the study highlights the importance of cybersecurity, interoperability, and scalability in enabling widespread adoption of optimized distribution systems. The findings underscore that the fusion of smart grid technology with optimization strategies can transform conventional distribution networks into adaptive, resilient, and sustainable energy infrastructures, capable of meeting future electricity challenges.

This paper concentrates on the organizational and communication aspects of development of the smart grid technologies. The paper highlights the potential of decentralised electricity generation for generating electricity from less energy-intensive and cost-efficient sources. It shows that renewable and unconventional energy sources may be integrated into decentralised electricity grids – the generation lines that have an intelligent grid. In addition, the paper focuses on the benefits and risks of different smart grid applications and their impact. We show that smart grids have the potential to minimise costs, but the use of smart grid technology also affects the level of risk, so the organizational and communication aspects are of a great importance.

Achieving a low carbon economy has been the focus of Hong Kong in recent years. Strategies are put forth to support sustainable energy, because Hong Kong has inadequate local and renewable energy reserves. Smart grid technologies have benefited many countries in the world, and countries such as the United States, the United Kingdom, China, and South Korea are exploring this new green energy strategy. Hong Kong’s power companies have considered smart grid technologies, conducting pilot projects to test their local feasibility. In this research, stakeholders’ perspectives of the current status of smart grids are overviewed in Hong Kong from the angle of policy aspect. Stakeholder theory is utilized as the framework for understanding and analyzing the perceptions of stakeholder groups. An integrated and modified stakeholder power-interest matrix was developed for analyzing level of power and interest of stakeholder groups on smart grid from policy dimension.
\n
\nThrough the course of this research project, qualitative interviews were conducted for 11 interviewees with subjectsfrom1six stakeholder groups, including: academics, advisory bodies, business, government, non-governmental organizations, and power companies. Follow-up quantitative questionnaires were distributed to the same target group for stakeholder analysis and to map the level of power and interest of stakeholder groups regarding smart grid policy development in Hong Kong. The data collected from interviews were compared with and contrasted against each stakeholder groups and other countries, with a view to identifying common motivations, barriers, and policy suggestions. The findings reveal that the six stakeholder groups hold medium to high power and interest in smart grid policy development in Hong Kong.
\n
\nCommon motivations identified by local stakeholder groups include: the right to choose their own energy mix for power generation, potential behavioural change via smart meter and tariff restructuring, possible energy savings and emissions reductions for the environment, and corporate social responsibility. The most significant motivation for smart grid development shared with other countries is the goal of achieving low carbon economy and energy efficiency.
\n
\nShared barriers perceived by the six stakeholder groups are: unreliable renewable power supplies, significant capital investments required, impracticalities of supplying electricity back to the grid, transfers of additional power generation costs to consumers, and limited smart grid knowledge by the public. The most significant barrier shared with international countries is funding mechanism, yet it may be difficult for Hong Kong to secure funding from the government because of problems of trust. 
\n
\nThree stages of recommendations are suggested. Short-term recommendations centre on the policy development direction of smart grid in Hong Kong, and include implementing dynamic pricing, undertaking a large-scale pilot program and establishing an awareness campaign (funded by the government)for educating the general public. Medium-term recommendation is to establish a joint green fund with the contributions of companies with large carbon footprints. Long-term recommendations include market liberalization and increases in market competition.

Game Theory in Smart Grids: Strategic decision-making for renewable energy integration

Smart grid technologies are expected to increase system efficiency and reliability using advancement in automation, communication, computation, and optimization. Several control algorithms have been developed or enhanced for operation and control of smart distribution grid. In recent years, volt/var control (VVC) algorithms have been proposed for energy saving in distribution systems due to advancement provided by smart grid automation and control. VVC helps to lower distribution feeder voltage to decrease energy consumption. However, quantification of this impact is hard due to several external factors such as weather and end users' behavior. On the other hand, existing evaluation methods of VVC algorithms are either not suitable for long-term study or intrusive. This paper addresses these issues by proposing a new technique to estimate “distribution system demand without smart grid implementation” utilizing “data measured from system with smart grid implementation.” Interdependence of voltage and load is considered based on estimated load characteristic. Our key contribution is developing a method for quantifying the real-time energy saving of smart grid automation and control focused on VVC and implementing in an electric utility in eastern Washington, USA. The algorithm is developed using both commercial and open-source software.

Smart grid technologies and applications

The ever-increasing number of electric vehicles (EVs) circulating on the roads and renewable energy production to achieve carbon footprint reduction targets has brought many challenges to the electrical grid. The increasing integration of distributed energy resources (DER) in the grid is causing severe operational challenges, such as congestion and overloading for the grid. Active management of distribution network using the smart grid (SG) technologies and artificial intelligence (AI) techniques can support the grid's operation under such situations. Implementing evolutionary computational algorithms has become possible using SG technologies. This paper proposes an optimal day-ahead resource scheduling to minimize multiple aggregators' operational costs in a SG, considering a high DER penetration. The optimization is achieved considering three metaheuristics (DE, HyDE-DF, CUMDANCauchy++). Results show that CUMDANCauchy++ and HyDE-DF present the best overall results in comparison to the standard DE.
