Summary: This study analyzes the path to net-zero energy for HVAC + PV systems, determining optimal combinations for different climate zones and providing a template for predicting net-zero systems in areas beyond the 12 studied. Geothermal HVAC system + PV is favored in climates with significant winter heating demand, while baseline + PV is preferred in cooling-dominant climates, with annual household savings exceeding $3,900 and $3,500 respectively. Patterns in local soil properties, sun intensity, and financial incentives allow for nationwide net-zero system predictions.

Summary: This study investigates the feasibility of implementing zero energy buildings in Muscat, Sultanate of Oman. Climate maps were created using raw climatic data from meteorological stations in the region, and surfaces with the highest solar energy were chosen. Special design elements such as thermal insulation and canopy were considered, and the number of solar panels needed was calculated. The modeling shows that installing PV panels as canopies can compensate for the energy shortage.

Summary: In order to consider crop growth and reduce energy consumption, this study optimized and retrofitted a typical solar greenhouse in a cold climate into a net-zero energy solar greenhouse. Passive insulation and flexible photovoltaic techniques were combined, and optimization cases were proposed based on simulation and analysis. The optimal case was determined using a multi-objective entropy weight method, considering energy saving, carbon reduction, payback period, and cost. The key finding is that the passive energy-saving retrofit case (a) & PV1 is the optimal NZESG case.

Summary: Solar PV-based autonomous mini-grids are a cost-effective and reliable option for rural electrification. However, the high initial investment cost for renewable energy technologies poses a challenge for rural communities. By implementing demand-side management (DSM), the cost-efficiency of mini-grids in rural areas can be improved. This study aims to determine the impact of DSM implementation at a category level on the cost-effectiveness of mini-grid components sizing for different load categories.

Summary: Transitioning towards low-carbon energy systems requires increasing residential Photovoltaic (PV) contribution through PV self-consumption, which can be supported by adopting PV self-consumption policies and incorporating batteries. However, it is crucial to assess and mitigate the technical impacts of PV policies on distribution networks. Implementing a two-stage planning framework that optimizes PV and battery sizes, and evaluates impacts on distribution networks through Monte-Carlo simulations, is essential for achieving sustainable energy goals.

Summary: Due to the ban on petrol and diesel car sales in the UK by 2030 and the nation's commitment to net-zero emissions by 2050, the growth rate of electric vehicles (EVs) is expected to increase significantly. However, barriers such as charging infrastructure, ownership costs, and battery expenses still hinder the adoption rate. This study aims to address these barriers by exploring the value of EVs for different user classes, specifically focusing on ownership costs and battery expenses.

Summary: This paper proposes a novel two-stage framework for net load forecasting in areas with limited observability and high behind-the-meter (BTM) photovoltaic (PV) generation. The framework disaggregates the net load measurements into the pure load and PV generation using observable customer profiles, and then separately forecasts the PV generation and pure load before combining the results for a net load forecast. It also introduces a compensator for correcting the net load forecast error using historical forecast errors. Results show that the proposed framework outperforms benchmark models in terms of net load forecast accuracy.

Summary: The study demonstrates that rooftop PV systems can increase the renewable fraction and reduce carbon emissions under various electric load scenarios. The 12 kW PV system is the preferred choice, but requires a long discounted payback period. Analyzing factors such as PV module price and tariff rate can help lower NPC and shorten the payback period.
