Addressing the Security risk of a Massive Deployment of Photovoltaic Power for Electric Power Systems

2023-08-01T15:41:44+00:00

Future electric power systems will incorporate a high percentage of Photovoltaic (PV) power generation as a means of mitigating environmental issues including global warming and energy depletion. The author observes that if the increase in uncertainties brought about by the PV penetration cannot be prevented, then it will be difficult to carry out the N-1 security level. To ensure the N-1 security requirement is met despite the uncertainties, paper has suggested a new notion of "robust power system security" along with many conditions to be met. In this research, and offer a model of uncertainties caused by PV generation, and use robust power system security to guide our choice of parameters. Next, simulate the system to learn more about, how PV and load disconnections affect stability, and how Fault Ride Through (FRT) and Dynamic Voltage Support (DVS) influence stability. Finally, it is demonstrated that the massive penetration of PV would significantly raise the complexity of burden jobs in future power system operation planning and real-time operation.

Emerging Frontiers of Public Safety: Synergizing AI and Bioengineering for Crime Prevention

2023-08-25T09:04:32+00:00

The convergence of artificial intelligence (AI) and biological engineering technology (BET) can potentially revolutionize public safety efforts. However, the responsible use of these technologies requires crucial considerations. This study employed an exploratory sequential mixed-method to examine the governance mechanisms apropos AI and BET in the context of crime prevention in the Philippines. It identifies several key components that contribute to establishing governance mechanisms, including multisectoral agencies, legislative initiatives, and regulatory frameworks. The study also identifies a 3-factor model for the governance convergence of AI and BET in public safety. These factors include empowerment and sufficiency, ethical considerations, and laws and regulations. The findings underscore the notable implications of integrating AI and BET into public safety efforts, such as improving surveillance systems, proactively preventing public health crises, and optimizing emergency response capabilities. However, ethical considerations and regulatory guidelines must be in place to address privacy concerns and mitigate potential risks associated with these technologies. The convergence of AI and BET also presents opportunities for sustainability. Nevertheless, concerns arise regarding its improper utilization. Based on the study's findings, policy recommendations are directed at ethical considerations, governance and regulation, and sustainability. These policy actions aim to address the opportunities and challenges associated with the convergence of AI and BET in public safety, ensuring responsible and beneficial use within the framework of Public Safety 4.0.

An overview of the energy segment of Indonesia: present situation, prospects, and forthcoming advancements in renewable energy technology

2023-08-19T08:37:03+00:00

The rising usage of fossil fuels increases greenhouse gas (GHG) emissions, leading to global climate change. Thus, addressing global environmental challenges requires a widespread switch from fossil fuels to renewable energy. Renewable energy reduces GHG emissions, extreme weather, and climate change while boosting energy efficiency. Indonesia ranks among Asia-Pacific's top five renewable energy producers. Indonesia, a vast country with abundant natural resources, has seen a rise in renewable energy demand as consumption has increased. Thus, this study examines Indonesia's renewable and sustainable energy technologies' existing position, possibilities, and future improvements. With 420 gigawatts (GW) of theoretical renewable energy capacity, Indonesia has great potential. This capacity includes 208 GW of solar, 75 GW of hydro, 61 GW of wind, 33 GW of biofuel, 24 GW of geothermal, and 19 GW of micro-hydro. The need to increase renewable energy consumption in Indonesia is driven by environmental and economic growth laws. This review study is expected to guide future research on renewable energy technology in Indonesia. This study would guide energy-related policies, particularly renewable energy ones, to meet future demands and goals.

A concise review of technologies for converting forest biomass to bioenergy

2023-08-06T11:29:09+00:00

The use of biomass is vital in reducing the negative effects of rising fossil fuel consumption. Given its quantity and diversity, forest biomass has garnered a lot of interest among the many kinds of biomass. This study evaluates the various strategies for transforming woody waste into usable biofuels. Carbon dioxide emissions from traditional energy generation systems could be mitigated through the direct utilization of forest biomass. Low energy conversion rates, as well as soot emissions and residues, are some of the problems that come up when directly using forest biomass. The sustainability of direct energy generation from forest biomass is also seriously threatened by the lack of constant access to biomass. Co-combustion with coal and pelletizing biomass is two solutions proposed for this issue. Co-combustion of forest biomass with coal has the potential to lower the process's emissions of carbon monoxide, nitrogen oxides, and sulfides. This article reviews and discusses the biochemical and thermochemical mechanisms that can transform forest biomass into a variety of liquid and gaseous biofuels. Future research using cutting-edge sustainability assessment tools like life cycle assessment, exergy, etc. should investigate the sustainability of forest biomass conversion processes to bioenergy further.
