This paper proposes an economic dispatch strategy for the electricity system with one generation company, multiple utility companies and multiple consumers, which participate in demand response to keep the electricity real-time balance. In the wholesale markets, multiple utility companies will commonly select a reliable agent to negotiate with the generation company on the wholesale price. It i...

Prior to the deregulation trend, electricity prices were highly regulated and were usually fairly predictable generators and wholesalers knew their production costs and revenues, and consumers knew their electricity costs. However, deregulation has caused electricity to become the most volatile of the commodities. Not only is the demand for electricity highly variable, but the inability to stor...

During periods of market stress, electricity prices can rise dramatically. Electricity retailers cannot pass these extreme prices on to customers because of retail price regulation. Improved prediction of these price spikes, therefore, is important for risk management. This paper builds a time-varying-probability Markov-switching model of Queensland electricity prices, aimed particularly at for...

We present an empirical analysis of restructured electricity prices. We study the distributional and temporal properties of the price process in a non-parametric framework, after which we parametrically model the price process using several common asset price specifications from the asset-pricing literature, as well as several less conventional models motivated by the peculiarities of electrici...

Energy carriers are one of the most important inputs in the agricultural sector. These inputs have been the foundation of the development and transition of the agricultural sector from the traditional stage to the industrial stage. The energy per capita marginal consumption in Iran’s agricultural sector is 3.2 times greater than its global average. Therefore, it is essential to save and optimal...

Identifying the factors that influence electricity demand in the continental United States and mathematically characterizing them are important for developing electricity consumption projections. The price elasticity of demand is especially important, since the electricity price effects of policy implementation can be substantial and the demand response to policy-induced changes in prices can s...

This paper aims to evaluate the forecast capability of electricity markets, categorized by numerous major characteristics such as non-stationarity, nonlinearity, highest volatility, high frequency, mean reversion and multiple seasonality, which give multifarious forecasts. To improve it, this investigation proposes a new hybrid approach that links dual long-memory process (Gegenbauer autoregres...

In this paper, the price elasticity of electricity demand, representing the sensitivity of customer demand to the price of electricity, has been estimated for South Australia. We first undertake a review of the scholarly literature regarding electricity price elasticity for different regions and systems. Then we perform an empirical evaluation of the historic South Australian price elasticity, ...

this paper expands a model different from existing models to analyze the cost and benefit of areinforced concrete solar chimney power plant (rcscpp) built in the desert regions of iran.based on the model and some assumptions for values of parameters, this paper calculates totalnet present value (tnpv) and the minimum electricity price in each phase by dividing the wholeservice period into four ...
