Summary: This article introduces a power management scheme for an integrated wind-solar renewable power generation system. The scheme utilizes a time-of-use electricity pricing mechanism to manage power exchange with the grid, and includes a battery energy storage for price arbitrage functionality. Additionally, the system control strategy incorporates a novel adaptive kernel width maximum correntropy criterion strategy.

Summary: This paper reviews recent studies on the equity of residential electricity tariffs in the context of the increasing distributed renewable energy sources. It identifies three main areas of focus in these studies: normative concerns, quantifying tariff fairness, and quantifying transitional fairness of pricing decisions. The paper also identifies research gaps and provides a comparative analysis of methodological choices. This review offers a broader perspective on the impact of distributed renewable energy sources on distributional concerns in residential electricity pricing for researchers and policy-makers.

Summary: Electricity tariffs play a crucial role in the decision-making process of end-users and have a significant impact on load energy management and environmental outcomes. This review paper examines various electricity tariff designs used worldwide, provides a detailed comparison, and discusses their advantages and disadvantages. The study also focuses on the electricity tariffs utilized in Egypt, a major country in the Middle East and North Africa regions, and proposes solutions for tariff improvement in the region.

Summary: The merit order effect describes the phenomenon of a decrease in electricity prices due to increased renewable energy capacity, but it is temporary due to slow capacity adjustments. Concerns about the adverse consequences for conventional power plants resulting from renewable capacity are partially justified, as renewables compete with base load to a limited extent.

Summary: Renewable energy sources (RES) in Uganda face challenges in terms of affordability and theft. A study conducted a probabilistic assessment to categorize households based on electricity affordability in urban and rural areas. The study proposed alternative billing schemes to enhance legal connection and consumption of electricity. Results showed higher theft losses in rural households and a significant difference in revenue collected between urban and rural areas due to the number of legally connected households and their consumption levels. The study also highlighted the high initial connection fee and the below-average affordability of electricity for both rural and urban households in Uganda.

Summary: The extensive growth of variable renewable energy integration presents challenges for power systems and markets, requiring flexibility to adapt to changes. Studies on short-term market pricing schemes show the importance of including flexibility features to incentivize agents to meet systemic flexibility requirements.

Summary: The paper investigates the impact of electricity energy pricing dynamics on the operational and economic performance of a PV-battery-based microgrid in Norway. It is found that grid buying price has a greater impact on the cost of energy generation compared to the grid selling price. Additionally, sensitivity analysis shows that battery cost has the highest impact on the cost of energy generation, followed by PV cost and grid tariffs.

Summary: The National Electricity Market (NEM) in Australia experienced its first market suspension from June 15-23, 2022, primarily due to insufficient generation capacity. This incident is significant as it occurred in a major energy exporting country. In this letter, we provide an overview and analyze the impacts of the incident. We identify three underlying causes of the market suspension from the perspectives of market regulation, electricity supply, and electricity demand, and propose four recommendations for the evolution of market mechanisms to enhance power supply security.

Summary: The study compares various flexible tariffs for prosumers' electricity management, finding that real-time pricing tariff increases retailer profits but leads to the largest price volatility for prosumers, while time-of-use and critical-peak-pricing tariffs only yield mild additional profits for retailers and uncertain revenues due to the multiplicity of optimal plans from prosumers.

Summary: This study models an energy community under different technical system configurations subject to different electricity tax and electricity grid tariff schemes to determine flexibility potentials and effects on the surrounding energy system. It is found that unless incentivised to reduce electricity grid imports, or that import capacity is otherwise restricted, the electrification of energy communities will significantly increase the electricity import from the surrounding electricity grid and thus increase the required electricity grid capacity. Most notably, capacity payments prove an effective measure in this regard.

Summary: The expansion of wind and solar energy has primarily led to decarbonization of the electricity sector. Power-to-gas (PtG) is seen as a solution for decarbonizing other sectors, but integrating PtG into electricity markets faces challenges due to current generation technologies. The design of electricity markets and carbon pricing should create incentives for utilizing PtG.
