Abstract- In a typical competitive electricity market, a large number of short-term and long-term contracts are set on basis of energy price by an Independent System Operator (ISO). Under such circumstances, accurate electricity price forecasting can play a significant role in improving the more reasonable bidding strategies adopted by the electricity market participants. So, they cannot only r...

In an electricity market, every generation company (GENCO) attempts to maximize profit according to other participants bidding behaviors and power systems operating conditions. The goal of this study is to examine the optimal bidding strategy problem for GENCOs in energy and spinning reserve markets based on a hybrid GA-heuristic optimization algorithm. The heuristic optimization algorithm used...

Reliable and efficient operation of deregulated electricity markets requires supply and demand elasticity. This paper presents incentive control of spinning reserves in electricity multi-markets using game theory. Interruptible load contracts (ILC) could reduce the amount of spinning reserve requirements during system contingencies such as transmission congestion. It is shown that the power uti...

Due to uncertain nature of wind and photovoltaic power units, the participation of this units in electricity markets is subjected to significant deviation penalties. This issue leads to despondency or even admission of these units in the competitive environment. With regard to this fact that the low deviations are available when predictions are performed in a short-term horizon and also distrib...

Traditionally, conventional generation unit was used to provide ancillary services e.g. reactive power support, and spinning reserve. Nonetheless, with the emergence of highly penetrated distributed energy resources (DERs) systems and considering how beneficial they can be; it appears reasonable to use them as reactive power providers. Therefore, this paper introduces a new procedure for DERs t...

This study addresses a stochastic structure for generation companies (GenCoʼs) that participate in hydro-thermal self-scheduling with a wind power plant on short-term scheduling for simultaneous reserve energy and energy market. In stochastic scheduling of HTSS with a wind power plant, in addition to various types of uncertainties such as energy price, spinning /non-spinning reserve prices, unc...

This paper presents a comprehensive framework model of a distribution company with security and reliability considerations. A probabilistic wind farm, which is a renewable energy resource, is modeled in this work. The requirement energy of distribution company can be either provided by distribution company’s own distributed generations or purchased from power market. Two reliability indices as ...

This document proposes a definition of spinning reserve. It also compares the amount asked by TSOs in several systems according to this definition. What is spinning reserve?

This paper solves reliability constrained unit commitment problem (UCP) for a composite power system network using network equivalent technique. Here, the integration of generation and transmission system reliability forms a composite power system model. The inclusion of load forecast uncertainty for the solution of unit commitment problem will give more accurate assessment of spinning reserve ...

this paper proposes a novel technique for solving generation scheduling and ramp rate constrained unit commitment. a modified objective function associated with a new start-up cost term is introduced in this paper. the proposed method is used to solve generating scheduling problem satisfying srr, minimum up and down time as well as ramp rate constraints. two case studies are conducted to implem...
