This paper considers the influence of promotion instruments for renewable energy sources (RES) on a multi-energy modeling framework. In Europe, so called Feed-in Tariffs are successfully used as incentive structures to increase the amount of energy produced by RES. Because of the stochastic nature of large scale integration of distributed generation, many problems have occurred regarding the qu...

Integrating large-scale micro-generation in distribution grids is challenging for distribution grid operators, particularly when renewable energy sources (RES) and micro-cogeneration are involved. In this paper we contend that recent developments in multiagent decision making under uncertainty can positively contribute to safe, efficient and costeffective operation of future distribution grids.

Recently, there has been a growing interest in the production of electricity from renewable energy sources (RES). The RES investment is characterized by uncertainty, which is long-term, costly, depend on feed-in-tariff and support schemes. In this paper, we address the real option valuation (ROV) of a solar power plant investment. The real option framework is investigated. This framework consid...

Energy as a geopolitical factor has gained a special occasion in power games of the world and access to energy resources has become a strategic importance for all levels of hierarchy of global power. Hormozgan province is one of the industrial provinces of Iran and this subject has caused to has been growing energy consumption in the province. Limited fossil energy resources and the problems of...

The objective of this paper is to analyse the design of market mechanisms that provide support for the adoption of renewable energy sources (RES) into the electricity system. Once RES become a significant share of the generation portfolio, the reliable and secure operation of the electricity system is threatened. The underlying question is how to better manage the uncertainty of these RES, spec...

In this paper, a two-level optimization model of mixed quadratic integer programming (MIQP) is presented in order to optimally operate microgrids under worst-case output conditions of renewable energy sources. This two-level model is divided into two high-level and low-level problems. In the high-level problem, the goal is to reduce energy loss and load shedding in the demand response program, ...

Base station sites (BSSs) powered with renewable energy sources have gained the attention of cellular operators during the last few years. This is because such “green” BSSs impose significant reductions in the operational expenditures (OPEX) of telecom operators due to the possibility of on-site renewable energy harvesting. In this paper, the green BSSs power supply system parameters detected t...

Promoting renewable energy sources (RES) has been addressed a key strategy for mitigating climate change, the governing in which has turned out a challenging and protracted task for the EU. There is often an implicit assumption that concern for climate change drives energy policy, but a closer look at the development of European RES policy indicates how EU governors have had to confront a range...

The paper presents methods for assessing economic, resource and environmental efficiency of energy supply systems and ways of its improvement, the main of which are the development of cogeneration and renewable energy sources (RES). The problem of allocating fuel and financial costs in the case of the combined production is solved. The methods allow determining specific indicators of supplied p...
