Security Price

The deregulation of power system brings a strong impact on all aspects of power industry, and especially the risk on the maintenance of system security. The problem is addressed and researched in this paper. Meanwhile, the paper presents a new price mechanism—security price, which is able to stimulate market participants to actively maintain system security. In addition, security price can also exert its economic leverage to alleviate the congestion of power network and the shortage of short-run capacity.

Regional Market

The paper is result of research different cross-border electricity trading mechanisms impact. Focus is on investments in generation and transmission power system facilities in regional market. Assumptions include efficient market coupling mechanism (with more bidding zones), use of additional investment indicators (like social welfare and congestion cost) and security of supply issues (capacity mechanisms). There is discussion on cost benefits analysis for particular market participants and there is possibility of risk reduction for regional power system expansion. It is shown current state-of-the-art, problems and trends in solving some aspects of market integration and investment issues. In some cases smaller and well defined bidding areas are absolutely essential in order to ensure system security and economic efficiency. There is no single criterion for power system expansion but it is possible to use combination of incentive schemes and possible through one index for cross-border trade. Risk management for cross-border electricity trading through several areas needs to be upgraded with use of financial transmission rights like weighted average area prices, respectively. Regional power system security is closely associated with timely investments in energy supply in line with economic development and environmental needs. Security of supply indicator is deriving an estimation of security of supply improvement from the market based simulation results when a generation or transmission investment project is implemented. All researched makes market integration and investments in Europe more efficient and gives more correct signals to market participants in regional market.

Security Pricing

Under power market environments, generator companies and power users are economic decision-makers and the ISO is the security decision-maker. The non-unique solution of security decisions may result in unfairness. At the same time, more and more power systems are operating near their security limits, thus the influence of uncertainty factors to security can not be ignored. To solve the above problems, the presented security pricing model in this paper suggests that security prices are calculated and released, which inducts and excites the market-participants separate decision-making, thus system security is maintained. Influences of the uncertainties of power loads and fault parameters to system security are taken into account. Furthermore, the system security and economy are unified in the model.

Key Issues

To reach the “30·60” decarbonization target (where carbon emissions start declining in 2030 and reach net zero in 2060), China is restructuring its power system to a new energy-based one. Given this new situation, this paper reviews previous studies on the power market and highlights key issues for future research as we seek to adapt to the new power system (NPS). Based on a systematic literature review, papers on the operational efficiency of the power market, participants’ bidding strategies and market supervision were identified. In a further step, papers with high relevance were analyzed in more detail. Then, key studies that focused on market trading under China’s new power system were picked out for further discussion. New studies were searched for that pertained to new energy mechanisms and bidding, the transition from coal-fired power, flexible resources and the technical applications of simulations. The quantitative analysis supports the construction of a basic paradigm for the study of power markets that is suitable for the new power system. Finally, the theoretical basis and application suggestions for power market simulations are introduced. This study summarized the existing research on the power market and further explored the key issues relating to the power market as it adapts to the NPS, hoping to inspire better research into China’s power sector, and promote safe, low-carbon, and sustainable development in China’s power industry.

Second Peak

A model of power market with a simple market clearing price mechanism on microgrid is considered. Market participants are consumers, prosumers with energy storage systems (ESS), and the power company as a guaranteed supplier. Prosumers charge their ESS in the first off-peak period with low prices from the power company and can decrease their demand or sell energy in the market through discharging the ESS in the second peak period. The strategic behavior of participants and their influences on a system state are postulated as the goal of work. Some use cases and model elements are discussed.
