This paper proposes a novel dynamic pricing scheme for demand response with individualized tariffs by consumption profile, aiming to benefit both customers and utility. The proposed method is based on the genetic algorithm, and a novel operator called mutagenic agent is proposed to improve algorithm performance. The demand response model is set by using price elasticity theory, and simulations are conducted based on elasticity, demand, and photovoltaic generation data from Brazil. Results are evaluated considering the integration effects of renewable energy sources and compared with other two pricing strategies currently adopted by Brazilian utilities: flat tariff and time-of-use tariff. Simulation results show the proposed dynamic tariff brings benefits to both utilities and consumers. It reduces the peak load and average cost of electricity and increases utility profit and load factor without the undesirable rebound effect.

Micro Grid

With the integration of more variable renewable energy, the need for storage is growing. Rather than utility scale storage, smart grid technology (not restricted, but mainly involving bidirectional communication between the supply and demand side and dynamic pricing) enables flexible consumption to be a virtual storage alternative for moderation of the production of variable renewable energy sources on the micro grid level. A study, motivated with energy loss allocation, electric demand and the legal framework that is characteristic for the average Serbian household, was performed using the HOMER software tool. The decision to shift or build deferrable load rather than sell on site generated energy from variable renewable energy sources to the grid was based on the consumer's net present cost minimization. Based on decreasing the grid sales hours of the micro grid system to the transmission grid from 3,498 to 2,009, it was shown that the demand response could be included in long-term planning of the virtual storage option. Demand responsive actions that could be interpreted as storage investment costs were quantified to 1?2 per year in this article.

Energy Justice

Over 90% of Uganda's power is generated from renewable sources. Standardised Implementation Agreements and Power Purchase Agreements create a long-term relationship between Generating Companies and the state-owned off-taker guaranteed by Government. The COVID-19 pandemic and measures to curb the spread of the virus have triggered the scrutiny and application of force majeure (FM) clauses in these agreements. This article reviews the FM clauses and considers their relevance. The authors submit that FM clauses are a useful commercial tool for achieving energy justice by ensuring the continuity of the project, despite the dire effects of the pandemic. Proposals are made for practical considerations for a post-COVID-19 future which provides the continued pursuit of policy goals of promoting renewable energy sources and increasing access to clean energy, thus accelerating just energy transitions.
