“…The first is that solar PV power generation has the same characteristics as wind power such as intermittent, volatile, and random. Once connected to the grids, it can result in voltage fluctuation, current and frequency instability, and impact on power quality and safety [101]. The second is particular to China.…”

China has experienced rapid social and economic development in the past 40 years. However, excessive consumption of fossil fuel energy has caused an energy shortage and led to severe environmental pollution. To achieve sustainable development, China is striving to transform its growth mode. Adopting renewable energy (RE) including solar photovoltaic (PV) power is an effective measure. How to promote the further development of solar PV power under the scenario of China’s aspirational target of carbon peak by 2030 and 20% RE ratio in the energy mix remains a theme that need to be addressed. This paper analyzes the potential opportunities and challenges confronting solar PV power in China. The analysis covers the dimensions of political, economic, social, and technological (PEST). The results revealed a significant prospect for the further deployment of solar PV power in the coming decades. The aggressive estimated installed capacity of solar PV power is expected to reach 80+ GW annually. To successfully achieve the goal of 80+ GW, barriers that hinder the further development of solar PV power have to be eliminated. Suggestions for policymakers include maintaining enforceability and continuity of policies, favorable financial supports, mandatory RE quotas for all parties, and supporting fundamental R&D. Suggestions for the solar PV industry include full utilization of integrated applications, set up an after-sales service network, collaborative innovation among the industry chain, and engaging in storage and hydrogen technology. The findings are greatly beneficial for policymakers and the solar PV industry.

“…Balanced power supply and demand represent an optimum condition and allow for more regional developments. Power grid interconnection is a significant tool for integrating energy resources [4][5] and back-to-back (BTB) converters are a vital part of power network interconnection systems. The BTB converter is also widely applied to flexible high voltage direct current power transmission, variable speed wind turbines in wind power generation systems, variable speed pumped storage plants and other applications.…”

DC‐side current compensation control in the rectifier terminal for power variations in back‐to‐back converters

Back-to-back (BTB) converters, which consist of an AC/DC rectifier cascaded with a DC/AC inverter, have been widely adopted in the interconnection of power systems. The DC link, being the interface between the rectifier and inverter terminals, is susceptible to disturbances, particularly from power fluctuations. Regardless of the magnitude of power or changes in the power flow direction, stability degradation will occur. To lessen the influence of power, a DC-link current compensation control scheme is proposed and applied to the rectifier terminal. The proposed scheme reduces the DC link impedance gain of the rectifier terminal to balance the impedance at both ends, and thus enhance stability and controllability. The scheme is applied to a BTB converter to improve the system's resistance to disturbance, regardless of variations in power magnitude or power flow direction. The accuracy of the theoretical analysis and the effectiveness of the proposed scheme are verified using simulations and a scaled-down experimental setup.

Concentrating solar power (CSP) plant, which has great controllability and scheduling flexibility, is a promising renewable energy power generation technology. The reasonable scheduling of a CSP plant can effectively reduce the operating cost of the integrated energy system (IES). In this context, a day‐ahead optimal coordinative operation model of the electric–thermal–gas IES considering CSP plant is proposed in this study with the objective function of minimising the operating cost of the IES. In the proposed model, the transmission delay characteristic of the thermal network is considered to reflect the large thermal inertia of the thermal network. Then, the incremental formulation for the piecewise linearisation and the second‐order cone relaxation method are utilised to transform the proposed non‐linear model into a mixed integer quadratically constrained programming model, which can be efficiently solved by CPLEX solver. The case study shows that the optimal operation model considering CSP plant has better performance in reducing the operating cost and promoting the wind power penetration when compared with the model considering photovoltaic. In addition, the scheduling flexibility of IES can be enhanced by the virtual thermal energy storage characteristic of the thermal network to reduce the operating cost and promote the wind power penetration of IES.
