In this paper, we analyze energy-efficient cellular networks that are based on renewable energy. We focus on hybrid energy base stations that are powered by renewable energy and power grid. This will provide the opportunity of obtaining green communication and integrating the renewable energy in the existing infrastructure at the same time. We propose a classification of the research problems and...
Micro-grid system is an integrated energy system asit consists of distributed energy resources (DERs) and multipleelectrical loads operating in parallel or islanded grid. Theprimary objective of this project is to examine whether Microgridimplementation can reduce the cost of energy. It can bedetermined through the modelling bus bar system; 5-Bus TestSystem and 26-Bus Test System. This application...
This paper makes a study about optimal supply of the energy service, using simulations of network operation scenarios, in order to optimize resources and minimize the variables: operation cost, energy losses, generation cost and consumers shedding. These simulations create optimal operation models of the network, allowing the system operator obtain knowledge to take pre-established procedures that...
The integration of renewable generation requires updates in transmission planning criterion and transmission pricing method. To reflect the recent updates in GB NETS SQSS, an improved ICRP method was developed. The main modification is the development of dual backgrounds - Peak Security (PS) background and Year Round (YR) background. The capacity sharing concept is introduced into YR background and...
The integration of renewable generation into power system brings challenges and threats for the power system operation and planning. Transmission congestion is one of the most intricate problems. Congestion cost links the short-term system operation and long-term network planning. But few literature study the congestion cost over long term. The main innovation of this paper is to employ statistical...
Over the past decade, there has been a resurgence of interest among system operators, policy makers and other grid stakeholders in the expanded utilization of energy storage (ES) and demand response resources (DRRs) to address power system economic and environmental concerns. In this work, we construct a general ES resource (ESR) model, which encompasses DRRs as a special case and explicitly represents...
Rural electrification, regardless of whichever electrification scheme is utilized (grid extension, mini grids, or autonomous energy home systems) has many potential benefits. In particular, hybrid mini grid power systems are potentially highly valuable electrification scheme for remote rural electrification in comparison with other electrification schemes but they involve significant complexities...
This paper presents a concept for a micro scale hybrid power plant design which utilizes animal draft power and biogas and it is well suited for rural farming villages with no access to electricity. A mechanism to extract animal draught power in an effective and efficient way is presented and the design procedure of the entire power plant is methodically discussed. In addition the estimated electricity...
Large and complex systems, such as the Smart Grid, are often best understood through the use of modeling and simulation. In particular, the task of assessing a complex system's risks and testing its tolerance and recovery under various attacks has received considerable attention. However, such tedious tasks still demand a systematic approach to model and evaluate each component in complex systems...
Modern electricity supply and distribution systems are evolving to integrate communications technologies and intelligent devices into what is broadly known as a Smart Grid. One area of Smart Grid development is the encouragement of a Smart Home where local electricity generation, storage, intelligent thermostats and electric vehicles can interact with home owners and the Smart Grid. This paper describes...
High penetration of distributed energy resources raises operational and market challenges. Existing incentives and tariff support can not be sustained with penetration growth and competitive market mechanisms are required at the micorgrid level. We propose a market mechanism to bring competitiveness at the microgrid level. In this dynamic matching mechanism, individual generators and load units meet...
Paper focuses on regional market and signals to market participants regarding investments and risk management in cross-border electricity trading. Choice of additional criteria for optimal power system expansion depends on several indicators like number of congested hours, congestion costs, maximization of social welfare, complex and simple investment indicator, optimization of the distribution of...
Photovoltaic powered distributed generation (PV-DG) is increasingly being embedded into electricity distribution networks worldwide with fast penetration rates. Among various elements which can limit a substantial dissemination of the PV-DG, one is the paucity of reliable forecasting methods for estimating production and exchange profiles of non-programmable sources with particular reference to solar...
This paper identifies the problem of the non-intrusive load monitoring method of load disaggregation into separate appliances, when some local generators based on renewable energy sources are connected to the same grid, as they may be mismatched with loads variable in time. Three approaches of electrical energy consumption disaggregation from the energy generated from local renewable energy sources...
The 21st century is named as green technology century and most of reasons for global warming such as air pollution, greenhouse gas and extra usage of oil and gas sources are being discussed to be replaced by a green idea, hence the United Nation, governments, universities around the world, and environmental activists alongside with scientists have already started researches and investigations over...
The smart grid shall not only integrate the intermittent resources (IRs) to meet the diverse demands of users and reduce the greenhouse gas emission, but also integrate Electricity Vehicles (EVs) as the energy storage facility to smooth the bulk power generation over time. In this paper, we model and analyze the impact of integrating IRs and EVs on the bulk power generation in the smart grid. In particular,...
This paper analyzes the competitive effect of two distinct marketing options for renewable electricity. I consider (1) a marketing regime that requires an independent system operator to transfer all available renewable electricity at zero prices to the spot market, and (2) a marketing regime where renewable plant operators directly sell their electricity on the spot or forward market. Similar marketing...
In a liberalised wholesale electricity market risk-averse market participants need some form of financial instrument to offset the risks of spot price variation across locations and across time. Some liberalised wholesale electricity markets seek to facilitate transactions across separately-priced nodes by making available an instrument known as a Financial Transmission Right (or FTR). But FTRs are...
In the UK, Ofgem, launched Project TransmiT to make an independent review on the charging arrangements of electricity transmission networks. One main proposal is the improved ICRP method for TNUoS charges. Improved ICRP method takes historical annual load factor to represent the year round performance of system users. However, it is widely suspected whether load factor can effectively reflect the...
The EU and its member states implement different policy tools aiming to promote a more sustainable power sector and achieve security of supply. Here carbon and renewable policies are the most prominently implemented (with the EU ETS established at the European level, and several national renewable policies implemented by the member states). In principle a distinction between price-based and quantity-based...
