All the internet services available these days are dependant and running in data centers. Companies like Google, Facebook, and Microsoft hosts millions of servers in their data centers to provide services to their users [19]. The enormous size of data centers leads to huge energy consumption. According to a news article, Google drew 260 MW of power in 2011 [6] that cost millions of dollars. Rec...

Under conventional models, subsidizing energy efficiency requires electricity to be priced below marginal cost. Its benefits increase when electricity prices increase to finance the subsidy. With high prices, subsidies are counterproductive unless consumers fail to make efficiency investments when private benefits exceed costs. If the gain from adopting efficiency is only reduced electricity sp...

This paper presents real time information based energy management algorithms to reduce electricity cost and peak to average ratio (PAR) while preserving user comfort in a smart home. We categorize household appliances into thermostatically controlled (tc), user aware (ua), elastic (el), inelastic (iel) and regular (r) appliances/loads. An optimization problem is formulated to reduce electricity...

The environmental impacts of fossil-fueled electricity drive interest in a cleaner electricity supply. Electricity from wind provides an alternative to conventional generation that could, in principle, be used to achieve deep reductions ð450%Þ in carbon dioxide emissions and fossil fuel use. Estimates of the average cost of generation—now roughly 4b=kWh—do not address costs arising from the spa...

The present deregulated electricity industry has evolved into a distributed and competitive industry in which market forces drive the price of electricity and reduce the net cost of electricity. However the competitions in these markets require identification of the use of transmission networks, mainly the participation of utilities in losses caused in the transmission lines. This is because th...

the new competitive environment changes the paradigm of power system operation. in the transmission area, open access process provides fair accessibility for all market participants. congestion management is one of the most important side effects of this new process. this paper proposes a new approach for congestion management which is based on both active and reactive re-dispatch of the networ...

In this paper, we study how datacenter energy cost can be effectively reduced in the wholesale electricity market via cooperative power procurement. Intuitively, by aggregating workloads and renewables across a group of datacenters, the overall power demand uncertainty of datacenters can be reduced, resulting in less chance of being penalized when participating in the wholesale electricity mark...

In the restructured electricity industry, electricity pooling markets are an oligopoly with strategic producers possessing private information (private production cost function). We focus on pooling markets where aggregate demand is represented by a non-strategic agent. Inelasticity of demand is a main difficulty in electricity markets which can potentially result in market failure and high pri...
