The aim of this thesis is to formalise cost allocation in the Dutch electricity sector by means of concepts from the theory of cost allocation and cooperative games. Consumers of electricity are connected to one of the seven voltage levels in the electricity grid. Most electricity is fed into the grid at the highest voltage level and is transported to lower voltage levels. Research in collabora...

The objective of the study is to analyse the conditions for connection of residential buildings in heat sparse areas to district heating systems in order to increase electricity production in municipal combined heat and power plants. The European electricity market has been assumed to be fully deregulated. The relation between connection of heat sparse areas, increased electricity and heat prod...

The Iranian electricity industry has been restructured following the global experiences. The main objective of restructuring is transition from natural monopoly towards competition in order to improve efficiency. Currently, the Iranian electricity market is performing as imperfect competition and Pay-as-Bid (PAB) auctions are the major trade mechanism in this market. This paper proves that Supp...

Waste-to-Energy is a challenging management in developing countries. There are many different technologies to generate electricity or heat from wastes. However, reuse and recycling are first prioritized as left a fraction of waste can be used as energy recovery. The initial cost to generate electricity from solid waste incineration is prohibitively high due to its cost of advance technology and...

The Basic Electricity Support Tariff (BEST) was designed to advance the welfare of poor households (UCT 2002). Specifically the South African government chose to supply 50kWh Free Basic Electricity (FBE) per month per household. We illustrate an alternative that would cost less, with larger benefits for the poor. By offering electricity for free, FBE distorts the energy choices of poor househol...

Industrial plants consume various forms of energy in their day-to-day operation, including electrical energy. By constructing in-house combined cycle and cogeneration plants, many industrial facilities are able to internally meet their steam and electricity demands. Depending on the availability, quality, and cost of the external electricity supply, an industrial facility has the flexibility to...

Due to the liberalization of countless electricity markets, load forecasting has become crucial to all public utilities for which electricity is a strategic variable. With the goal of contributing to the forecasting process inside public utilities, this paper addresses the issue of applying the Holt-Winters exponential smoothing technique and the time series analysis for forecasting the hourly ...
