Data-Driven Observability Enhancement in Active Distribution Networks via Optimal Co-Deployment of DGs and D-PMUs Using Hybrid APSO-ASDA |
| Notes |
The increasing deployment of renewable Distributed Generators (DGs) introduces operational uncertainty and observability challenges in Active Distribution Networks (ADNs). Traditional Supervisory Control and Data Acquisition (SCADA) systems lack the temporal resolution required for real-time monitoring. This paper proposes a data-driven framework for enhancing network observability through optimal co-deployment of DGs and Distribution Phasor Measurement Units (D-PMUs) using a hybrid Accelerated Particle Swarm Optimization-Adaptive Spiral Dynamic Algorithm (APSO-ASDA). The objective is to maximize network observability with minimal measurement redundancy for improved Distribution System State Estimation (DSSE). Simulation results on the IEEE 13-bus ADN, modeled in MATLAB Simulink R2023b, showed ASDA optimal DG -D-PMU placement at buses 1, 4, with corresponding sizes of 340Kw(solar), and 445kW(wind) with D-PMU at 6, 7, 10, and 12. APSO DG placement is at bus 3 and 4 with a size of 60kW(solar), 400kW(wind), D-PMU at buses 6, 8, 9. The hybrid approach places DG at buses 1 and 3 with corresponding capacities of 110kW (solar) and 250kW (wind), and D-PMU allocation at buses 4, 6, 7, 8, 11 and 12. The hybrid algorithm achieved a rapid reduction in the cost function from 278.7 to 81.14 within the first 36 iterations, highlighting its effectiveness for real-time, data-driven applications. |

The Role of Engineers in Driving Nigeria’s Energy Transition and Industrial Competitiveness in the North-East. |
| Notes |
Nigeria’s Energy Transition Plan outlines an ambitious pathway to net zero emissions
by 2060, with significant implications for the power, industrial, transport, cooking, and oil and
gas sectors. Translating this vision into practice while preserving industrial competitiveness and
advancing equitable development remains a major challenge. The challenge is most acute in
the North-East. Persistent energy poverty, weak infrastructure, and limited industrial activity
have widened the development gap between the region and other parts of the country, including
the South-West, South-South, South-East, North-West, and North-Central. Delivering on the
Energy Transition Plan therefore requires more than national level targets. It demands a focused
mobilization of engineering capacity that responds to regional realities. This paper draws on
desk-based reviews of policy documents, peer reviewed literature, and empirical evidence to
clarify the technical, institutional, and educational roles of engineers in this process. These roles
include accelerating decentralized renewable energy deployment, integrating advanced energy
storage, stimulating local clean technology manufacturing, and developing a skilled, future
ready workforce. The paper concludes with prioritized policy recommendations to align
engineering practice, education, and innovation with Nigeria’s transition objectives and the
urgent need for sustainable industrial development in the North-East. |

Nigeria's Green Hydrogen Pathway: A Strategic Framework for Climate Neutrality and Energy Security |
| Notes |
Nigeria faces a dual challenge of energy poverty and the imperative to decarbonize its fossil fuel-dominated economy in alignment with its 2060 net-zero commitment. This paper explores the potential of Green Hydrogen (GH) as a cornerstone for a sustainable and secure energy future for Nigeria. Utilizing a comprehensive desk review methodology, we analyze Nigeria's abundant but underutilized renewable energy resources—solar, wind, and hydro—as a foundation for cost-competitive GH production. The study identifies significant barriers, including high capital expenditure, infrastructural deficits, and a nascent policy framework. Conversely, it highlights strategic opportunities in export markets, domestic decarbonization of hard-to-abate sectors, and local economic development through green ammonia and fertilizer production. We propose a multi-stakeholder pathway involving robust policy formulation, international collaboration, and substantial investment in research, development, and capacity building. The findings posit that a concerted national strategy towards a GH economy can simultaneously address Nigeria's energy trilemma: inequitable energy access, energy insecurity and environmental sustainability; foster industrial growth and solidify its role as a future leader in the global green energy market. |

An Innovative Smart Pilot Solar Drying System for Sustainable Agriculture in Sokoto State. |
| Notes |
Agricultural product drying systems preserve quality and extend the shelf life of harvested crops. Solar
drying reduces reliance on traditional methods, often contributing to deforestation and environmental
degradation. This work presents a sustainable process for preserving agricultural produce, helping to
improve food security and reduce post-harvest losses. Emerging trends include renewable energy
sources, automation and monitoring systems. Data shows many farmers lack drying structures and
equipment (80%), relying on direct sun drying with disadvantages. The designed system allows for three
different modes and input of drying parameters. The collector has a dimension of 1516 by 344mm, with a
tilt angle of the collector being 15°. The drying chamber has a dimension of 480mm by 500mm. The
chimney has a height of 200m and a diameter of 46mm. Research aligns with Sustainable Development
Goals (SDGs) for agriculture. The results showed the importance of deploying smart drying systems in
the state. |
