Abstract

With the increasing energy demand, the growing capacity of renewable energy sources and the impact of developing competition, it is desirable to manage the market with appropriate investments along with the electricity market and optimum load distribution. In line with this demand, supply security and energy quality play an important role day by day. This includes the production capacity and the long-term security of the system, reflecting the system's ability to stand in unexpected events and sudden load changes. The demand side seems to have insufficient support to the market for new capacity planning to ensure this coverage. This problem can be solved by producing additional capacity. Basically, it is aimed to reduce investment risk for production companies and / or investors and to provide higher supply security and lower price fluctuations to consumers. The concern of not investing in electricity generation capacity to meet the maximum load level has led to investments in capacity utilization in the form of capacity mechanisms of developed and developing states. In this study, an academic analysis of the capacity mechanism of the renewable energy resources and the capacity analysis of the capacity mechanism were made and expert opinions were presented, the latest developments in the energy market were examined and the reliability solutions that could be appropriate to the national electricity market were proposed

Highlights

  • POWER MARKETS are experiencing major changes in their investments in supply security and production capacity along with the search for improved technology and comfort

  • Production capacity varies depending on the increasing share of variable renewable energy sources in line with the needs developed

  • Our national power system in January 2018, the rules regarding the capacity mechanism to be operated by Turkish Electricity Transmission Corporation (TEIAS) were determined in order to establish an adequate installed power capacity, including the reserve capacity required for supply security in the electricity market, and / or to maintain reliable installed power capacity for long-term system security

Summary

INTRODUCTION

In the EU electricity sector, as in the electricity sectors of other countries, generally characterized by excess capacity supply, capacity shortages may occur in case of high demand from low-capacity power plants (due to lack of wind or sun, for example) This leads to concerns that there will be insufficient production capacity in relation to the load distribution to ensure the safety of my electricity supply. Capacity mechanisms are generally argued to help reduce the cost of large-scale wind energy development to reduce the likelihood of loss of load As a result of optimization, it is emphasized the importance of the capacity mechanism by identifying the most suitable type of heating system in terms of the heat load density in the unit area [3,4,5] This mechanism is defined as the administrative measure to ensure the desired level of supply security by charging production plants for the availability of resources. Non-coordinated capacities may disrupt cross-border trade and hinder the success of the Domestic Electricity Market in Europe [12,13]
