  7. Abstract:
  8. Electric industry has experienced a great revolution in the last two decades, which is known as restructuring and deregulation. Based on these fundamental changes, new commodities and concepts such as ancillary services have been introduced.Operating reserve is one of the most important types of ancillary services, which has great impact on the reliability of power systems. Determining the amount of required reserve, allocation between generating units and its cost allocation are the important topics that have been considered in many papers and with this important is considered in this thesis. According to the economic principles, invisible hand of market can facilitate global optimum, just when in the wholly competition environment, decisions are made decentralized. Based on this principle, in this thesis customers have the right to select their service provider and they have a chance to request their reliability requirement from the independent system operator.In this thesis a method is designed to manage reserve market that in the proposed model, more attention is paid to the reliability requirements of customers. Presenting a suitable and fair method for reserve cost allocation among customers with different requests from reliability is considered. Principally, the returning of customers' investment for reliability during system normal operation condition can't be clearly implemented, but when system encounters a generation deficiency, system operators use interruption factors for fairly dividing the shortage among customers in the real time.For achieving an acceptable reliability level in the power network, it is important for ISO to select an optimum value of reserve capacity for market operation. On the other hand, customers may have specific reliability requirements and hence, their designated value to the lost load may be different. Cost of satisfying this requirement can be more than the benefit of reserve provision. In these situations, ISO may prefer to apply involuntary load shedding. These facts imply that ISO should try to reach an optimum condition for satisfying demand requirements. Finally, proposes an algorithm for determining optimal reserve capacity based on a cost- benefit trade off. Proposed methods are applied to test systems and results showing the effectiveness of the proposed methods are also presented
