Efficient multi-year economic energy planning in microgrids
The primary goal of economic planning models is to capture microgrid economics under normal operating conditions, where normal operation should maximize the value of the microgrid system [6]. Here, a microgrid is defined as a self-sufficient energy system that serves a discrete geographic footprint, such as a college campus, …
Engineering Economics of Microgrid Investments
The proposed models can be used for analyzing the microgrid economic development and accordingly, determine the optimal size and combination of DERs to be installed. The proposed model alleviated the need for complex calculations, hence, allowing a fast and efficient study of microgrid planning. The obtained result showed that the …

Microgrid Dynamic Economic dispatching Considering Wind-Solar ...
The microgrid(MG) was widely concerned to solve energy pollution and scarcity crisis. A dynamic economic dispatch model considering wind and solar complementary characteristics is proposed in this paper. Firstly, the wind and solar complementary characteristics is modeled based on copula theory. Secondly, based on …
Microgrid Evolution Roadmap Engineering, Economics, and …
The Working Group was asked to identify the main elements required to justify, develop, and implement viable microgrids, which the Group defined as follows: Microgrids are electricity distribution systems containing loads and distributed energy resources, (such as distributed generators, storage devices, or controllable loads) that can be ...
The Economics of Microgrids
Afterwards, the role of microgrids in power systems through improved reliability, increased resilience, and enhanced power quality is presented. Next, critical microgrid features and technologies including microgrid power management and control, microgrid islanding, microgrid protection, microgrid communications, and …

With the increasing capacity of renewable energy generators, microgrid (MG) systems have experienced rapid development, and the optimal economic operation is one of the most important and challenging issues in the MG field. To reduce the overall generation cost of microgrids, a hybrid butterfly algorithm (HBOA) is proposed to …
The impact of policy on microgrid economics: A review
2020. TLDR. This work presents a detailed view on how the current policy scenario for the electricity sector in Brazil is prepared to absorb the concept of microgrids in both its technical and commercial scope and contributes to policy analysis that serve to leverage the insertion of microgrid in the context of the Brazilian energy sector. Expand.
Profitability of Hydrogen-Based Microgrids: A Novel Economic …
The current need to reduce carbon emissions makes hydrogen use essential for self-consumption in microgrids. To make a profitability analysis of a microgrid, the influence of equipment costs and the electricity price must be known. This paper studies the cost-effective electricity price (EUR/kWh) for a microgrid located at ''''La Rábida …
Research on the Optimal Economic Power Dispatching of a Multi …
The economic power-dispatching model of a multi-microgrid is comprehensively established in this paper, considering many factors, such as generation cost, discharge cost, power-purchase cost, power sales revenue, and environmental cost. To construct this model, power interactions between the two microgrids and those …
Reliability evaluation, planning, and economic analysis of microgrid ...
The interactive relationship between capacity planning and microgrid reliability are analyzed, which can improve the reliability and economy of microgrid under the access of RE and EVs. (2) A microgrid configuration method that takes into account reliability and economy is proposed, in the case of RE and EVs connected to the …
Portugal | OECD Economic Outlook, Volume 2022 Issue 1
Portugal. Real GDP is projected to grow by 5.4% in 2022 and 1.7% in 2023. Robust public investment, boosted by EU funds, and the return of tourism exports are set to support the recovery. Yet, the war in Ukraine, supply-chain disruptions and increases in energy and commodity prices will weigh on activity, lowering confidence and purchasing ...
Advances in Applied Energy
overall microgrid reliability. 1.2. Economic value of PV and BESS The economics of behind-the-meter PV and BESS has been well stud- ied. Many studies have assessed and optimized the economics of PV systems without storage as a function of building types [17], utility rate structure, ownership options, PV size, and PV costs [18] . Tools are avail-
