Abstract Europe and the United States, in particular, promote the deregulation of the electric power industry in favor of renewable energy generation. With an increase in renewable energy generation, thermal power generation has been switched to standby power. Ammonia, one of the storage and transport media for H2, is produced in a highly efficient oxyfuel IGCC (integrated coal gasification combined cycle) system with CO2 capture, for the future hydrogen-using society. Using ammonia as an industrial raw material, agricultural fertilizer, and transportation fuel, energy system can be established by combining renewable energy and thermal power generation. Therefore, it is possible to simultaneously construct a thermal power supply system suitable for backup power source owing to the fluctuation of the renewable power generation and to realize improvement of availability of the thermal power plant and the load-leveling. It will be an incentive to build a future zero-emission thermal power plant. In this study, an oxy-fuel IGCC power generation co-produced with ammonia and CO2 capture is proposed. Furthermore, the features and challenges of a gas turbine that fuels CO2-free NH3 are investigated. In particular, the combustion exhaust characteristics of ammonia/oxygen fired semiclosed cycle gas turbine combustor in comparison with those of the conventional fuels are clarified through a kinetic analysis.

Thermal Power Generation

<p>In China, there are many ways to generate electricity. Thermal power is used as the main way to generate electricity. Typically, thermal power mainly uses coal as primary power source, therefore it is often necessary to have a coal storage. Currently a closed coal yard if compared to others coal storage building: its construction taken up small area, it has large storage capacity per unit area, it has high site utilization rate, it has no dust during storage and discard process, environmental friendly, centralized control program is used in the coal field system, high degree of automation, can be unattended and others advantages are increasingly being adopted. The structure design of a closed coal yard has a crucial role in the efficiency of the entire thermal power generation. Therefore, a reasonable design is of closed coal yard is necessary in thermal power generation. This paper will focus on the study of the design of closed coal yard in thermal power plant.</p>

Renewable Energy Generation

With the advent of the new types of electrical systems that attach more importance to the renewability of the energy resource, issues arising out of the randomness and volatility of the renewable energy resource, such as the safety, reliability, and economic operation of the underlying power generation system, are expected to be challenging. Generally speaking, the power generation company can do a reasonable dispatch of each unit according to weather forecast and load demand information. Focusing on concentrating solar power (CSP) plants (wind power, photovoltaic, battery energy storage, and thermal power plants), this paper proposes a day-ahead scheduling model for renewable energy generation systems. The model also considers demand response and related generator set constraints. The problem is described as a mixed-integer nonlinear programming (MINLP) problem, which can be solved by the CPLEX solver to obtain an optimal solution. At the same time, the paper compares and analyzes the impact of concentrating solar power plants on other renewable energy generation and thermal power operation systems. The results show that the renewable energy generation system can lower power generation costs, reduce load fluctuation, and enhance the energy storage rate.

Renewable energy generation is no more an alternative rather it becomes a choice for the power generation to meet the upcoming energy demand. Considering the non- renewable energy unavailability, as well as, the environmental impact, renewable energy should be the first choice. Most of the power generation in Bangladesh comes from nonrenewable energy and a noticeable amount of energy is imported from abroad. As a developing country, it is not cost-efficient and never ensures energy security. To ensure long-term energy security, it is time to shift power generation from nonrenewable to renewable energy generation. This paper presents an approximate calculation for the renewable power generating plant cost and returning year. The cost calculation is done in the context of Bangladesh.

With the rapid growth of renewable energy generation, it has become essential to give a comprehensive evaluation of renewable energy integration capability in power systems to reduce renewable generation curtailment. Existing research has not considered the correlations between wind power and photovoltaic (PV) power. In this paper, temporal and spatial correlations among different renewable generations are utilized to evaluate the integration capability of power systems based on the copula model. Firstly, the temporal and spatial correlation between wind and PV power generation is analyzed. Secondly, the temporal and spatial distribution model of both wind and PV power generation output is formulated based on the copula model. Thirdly, aggregated generation output scenarios of wind and PV power are generated. Fourthly, wind and PV power scenarios are utilized in an optimal power flow calculation model of power systems. Lastly, the integration capacity of wind power and PV power is shown to be able to be evaluated by satisfying the reliability of power system operation. Simulation results of a modified IEEE RTS-24 bus system indicate that the integration capability of renewable energy generation in power systems can be comprehensively evaluated based on the temporal and spatial correlations of renewable energy generation.
