Electric power systems are entering a new realm of operations. Large amounts of variable generation tax our ability to reliably operate the system. Couple this with a greater reliance on the electricity network to serve consumer demand that is likely to rise significantly even as we drive for greater efficiency. Trade-offs between energy and environmental needs will be constantly negotiated, while...
This paper proposes a new mechanism to give added incentive to invest in new capacities in deregulated electricity markets. An optimization problem to maximize long term social welfare includes binary variables for the building of new facilities, and continuous variables for generation, i.e. the model is a mixed integer nonlinear program. The new mechanism also includes a new approach to calculate...
Plug-in hybrid electric vehicles (PHEVs) are the next big thing in the electric transportation market. While much work has been done to detail what economic costs and benefits PHEVs will have on consumers and producers alike, it seems that the more important question is “what impact will PHEVs have on distribution networks nationwide?”. This paper finds that the impact of PHEVs on the distribution...
With the challenge of climate change, many governments around the world are focusing on reducing emissions of carbon through energy efficiency improvements, particularly in the rapidly-growing electricity demand. There are great potentials in this sector for reducing emissions in both supply-side and demand-side. On the supply-side, thermal power plants are major contributors to CO2 emissions. Promoting...
Supplying a reliable, efficient, economic electrical service to all customers is the basic responsibility of utilities. However, increasing penetration of new customers in distribution grids as dispersed generation (DG), electric heating systems and electric vehicles (EV), makes conventional operation of energy supply systems difficult while meeting the aforementioned responsibility. Therefore, the...
Electricity markets are currently evolving to accommodate large scale penetration of wind generation. In this research, potential changes to the classification and role of wind generators in the Single Electricity Market (SEM), the market for Northern Ireland and the Republic of Ireland, are examined. The effect of wind generators opting to become price-making and the potential for wind generators...
This paper presents an analytical model for wind power investment. Most generation planning problems are formulated in multiperiod mixed integer programming with cost minimization as objective. We try to resort to finance literature for models able to systematically characterize return and risk. Real option theory is chosen. A primitive function is defined for the fuel cost able to be saved as the...
In response to the Kyoto protocol, the European Union (EU) introduced the Emission Trading Scheme (ETS), which adopts `cap-and-trade' market mechanism for CO2 emission trading. In this scheme, the emission allowances are allocated to each industrial installation and companies can buy and sell their allowances. In the electric power sector, the development of decision-making methods concerning emission...
Since models form the basis for most power system studies, power system model validation is an essential procedure for maintaining system security and reliability. The procedure may be viewed as a “top-down” approach to model verification; comparisons with measured data indicate the quality of the overall model. Analysis of the differences demonstrates which subsystem component models need to be revalidated...
The most significant energy consuming infrastructures and the greatest contributors to greenhouse gases in the US today are electric and freight/passenger transportation systems. Technological alternatives for producing, transporting, and converting energy for electric and transportation systems are numerous. Selecting from among them requires long-term assessment since these capital-intensive infrastructures...
Sustainability is the next significant trend to confront government agencies as evidenced by the world-wide focus on energy conservation and reducing green house gases. Recent environmental laws and legislation require agencies to address conservation in very specific ways. Given this goal of sustainability, what strategies initiatives, and measures can be implemented? One answer is the adoption of...
The Chilean electricity regulation introduced in 2008 an obligation to contract 10% of renewable energy, excluding large hydro, in the wholesale market. This paper assesses the impact of that obligation into the market, revises renewable projects that have been submitted for environmental assessment, the actual plants being built and the requirements they are imposing onto the transmission system...
