introduction despite the abundant renewable energy sources, the iranian energy sector relies almost entirely on fossil fuel energy resources. power sector is dominant source of co2emissions and responsible for about 35% of total co2 emissions in the country. additionally, long-term electricity demand of iran is expected to grow quickly, which in turn requires extensive investment to meet the gr...

We estimate the long-run economic value of variable renewable generation with increasing penetration using a unique investment and dispatch model that captures long-run investment decisions while also incorporating detailed operational constraints and hourly time resolution over a full year. High time resolution and the incorporation of operational constraints are important for estimating the e...

Electricity generation from renewable sources is growing rapidly, but the variability and uncertainty of renewable resources like wind and solar energy can increase the costs of supplying reliable electricity. Competitive markets for wholesale electricity are widely used in the United States, but the regulatory details that govern their treatment of stochastic resources can have significant eff...

Designing and implementing a renewable energy policy involves political decisions and actors. Yet most research on renewable energy policies comparatively evaluates instruments from an economic or technical perspective. This paper presents a case study of Ontario’s feed-in tariff policies between 1997 and 2012 to analyze how the political process affects renewable energy policy design and imple...

using photovoltaic systems is gradually expanded by increasing energy demand. abundance and availability of this energy, has turned to one of the most important sources of renewable energy. unfortunately, photovoltaic systems have two big problems: first, those have very low energy conversion efficiency (in act between 12 and 42 percent under certain circumstances). second, the power produced b...

The utilization of renewable energy sources in electric power systems is increasing quickly because of public apprehensions for unpleasant environmental impacts and increase in the energy costs involved with the use of conventional energy sources. Despite the application of these energy sources can considerably diminish the system fuel costs, they can also have significant influence on the syst...

Many countries and U.S. states have implemented rules, policies, and financial incentives to promote renewable energy adoption. Renewable Energy Certificates subsidize investment but their price is subject to market conditions. Uncertainty due to fluctuating certificate prices has allegedly discouraged investment in solar photovoltaic installation. In this paper, I assess the impact of certific...

The global electricity supply from non-hydro renewable energies, such as wind and solar, has being growing at a high rate, and it is expected that this trend persists. In China, Wind power is one of the most mature renewable energy technologies and it is possible to be utilized in large-scale. However, in the long run, the malicious competition will break the rule of the monopoly wind power mar...

We model dynamic competition in which firms make initial capital investment decisions followed by repeated entry and exit choices as demand fluctuates. We show a correspondence between competitive equilibrium and the solution to a planner’s problem, which establishes equilibrium existence and provides a platform for computation. We apply the framework to model electricity generator investment d...
