Pinch analysis techniques have been developed for a wide range of applications ranging from process plant thermal or water integration to financial and supply chain management. This paper presents a new application of pinch analysis. A scenario is assumed wherein energy sector planning takes place with carbon emission constraints arising from an effort to reduce climate change effects. A procedure...
There are regions in the Republic of Croatia (underdeveloped, devastated by war, depopulated, as well as islands and mountainous areas) which are still disconnected from the electricity network or where the current network capacity is insufficient. In addition, these regions have good renewable energy potential. Since the decentralized energy generation (DEG) covers a broad range of technologies,...
In this paper, we present the near-term analysis of capacity expansion under various uncertainties from the viewpoints of the decision-making process on the optimal allocation of investment and the value of information. An optimization model based on two-stage stochastic programming was developed using real data to describe the Japanese energy system as a case study. Different uncertainty parameters...
This work presents algebraic targeting techniques for energy sector planning with carbon (CO 2 ) emission and land availability constraints. In general, it is desirable to maximize the use of low- or zero-carbon energy sources to reduce CO 2 emission. However, such technologies are either more expensive (as with renewable energy) or more controversial (as in the case of nuclear energy...
The increasing demand for energy, especially from renewable and sustainable sources, spurs the development of small hydropower plants and encourages investment in new survey studies. Preliminary hydropower survey studies usually carry huge uncertainties about the technical, economic and environmental feasibility of the undeveloped potential. This paper presents a methodology for large-scale survey...
Based on 25 years of involvement in a number of important and representative political decision-making processes in Denmark and other countries, this paper presents the unified learning of some of the institutional barriers one will meet when radical technological changes such as the replacement of fossil fuel with renewable energy are to be implemented, and how to overcome such barriers. On the one...
Wind power technology is now a reliable electricity production system. It presents an economically attractive solution for the continuously increasing energy demand of the Marmara region located in Turkey. However, the stochastic behavior of wind speed in the Marmara region can lead to significant disharmony between wind energy production and electricity demand. Therefore, to overcome wind’s variable...
This paper studies the cost of energy (COE) for several emerging, fossil fuel power plants such as an integrated gasification combined cycle (IGCC) power plant, a natural gas combined cycle (NGCC) power plant, and a pulverized coal (PC) power plant under three different scenarios defined by the International Energy Agency (IEA). In order to compare the COE for each power plant more realistically,...
Energy procurement is a necessity which needs a deep study of both the demand and the generation sources, referred to consumers territorial localization. The study presented in this paper extends and consolidate the Shimon Awerbuch’s study on portfolio theory applied to the energy planning, in order to define a broad generating mix which optimizes one or more objective functions defined for a determined...
High fuel costs, increasing energy security and concerns with reducing emissions have pushed governments to invest in the use of renewable energies for electricity generation. However, the intermittence of most renewable resources when renewable energy provides a significant share of the energy mix can create problems to electricity grids, which can be minimized by energy storage systems that are...
During the last few decades, energy planning has focused on meeting domestic demand at lower total costs. However, global warming and the shared recognition of it have transformed the problem of energy planning into a more complex task with a greater number of issues to be considered. Since the key issue is to reduce greenhouse effects, governments around the world have begun to make investments in...
This paper proposes a model to minimize life-cycle costs of meeting the energy demand (power, heating, cooling) of a commercial building by integrating cogeneration, solar and conventional energy sources. The possibility to export the onsite produced power under a given legislative framework is also considered. The output of the model is twofold: optimal investment planning and optimal operating strategies...
Research efforts to analyse China's future energy system increased tremendously over the past decade. One prominent research area is China's first binding CO 2 emission intensity target per unit of GDP (Gross Domestic Product) and its impact on the country's economy and energy system. This paper compares 18 energy modelling tools from ten Chinese institutions. These models have been described...
In the light of European energy-climate package and its measures for increasing security of supply, decreasing the impact on environment and stimulating sustainability, Croatia as a new EU (European Union) member state needs to reconsider and develop new energy policy towards energy efficiency and renewable energy sources. Croatian long-term energy demand and its effect on the future national GHG...
Substantial social and environmental benefits can be achieved through regional DSM (demand-side management) strategies. Here, three DSM scenarios that vary in capital investment costs of technology retrofits were tested for the contemporary Northeastern US. These resulted in an 8.3–16.5% decrease in summertime regional electricity consumption. The lower power consumption achieved through DSM was analyzed...
Energy-environmental planning for transportation sector requires extensive data for energy carriers types, production, and consumption as well as vehicle technologies. However, in developing countries, where private transportation sector is growing at an enormous rate and energy-environmental planning is needed the most, the required relevant data are usually limited or unavailable. The objective...
Integrated, model-based energy planning particularly in cities and territories involves different planning and modelling activities, which, from a methodological point of view, can be divided into four phases. The analysis and findings of this study focus on planning “phase I”, which is devoted to preparation and orientation. Despite the importance of this planning phase, which is underlined in several...
The aim of the present research is to evaluate future primary energy consumption in the Italian thermoelectric sector. Despite its importance in the European context, researches addressing the primary energy consumption in the Italian power sector are not available in the literature. Therefore, to bridge this gap, a detailed representation of the power generation sector is proposed by modeling each...
Concerns related to climate change and security of energy supply are pushing various countries to make strategic energy planning decisions. This requires the development of energy models to aid decision-making. Large scale energy models are often very complex and use economic optimization to define energy strategies. Thus, they might be black-boxes to public decision-makers. This work aims at overcoming...
We introduce a new method for incorporating short-term temporal variability of both power demand and VRE (variable renewables) into long-term energy-economy models: the RLDC approach. The core of the implementation is a representation of RLDCs (residual load duration curves), which change endogenously depending on the share and mix of VRE. The approach captures major VRE integration challenges and...
