　　Since the beginning of this year, driven by favorable policies, the new energy industries such as photovoltaics, wind power generation, electrochemical energy storage, and pumped storage have developed rapidly, with a significant increase in installed capacity. New energy generation has become an important component of the new power system, which also makes it more complex than traditional power systems. In the future, it is expected that the installed scale of renewable energy will continue to grow rapidly, gradually completing the deep transformation of the energy system and achieving the goal of "carbon neutrality". Subsequently, how to achieve effective operation and maintenance management of photovoltaic power plants, energy storage, and supporting electrical facilities through the system, so as to ensure their safe and reliable operation.

　　one Development Trends of Photovoltaic and Energy Storage in 2023

　　According to data from the New Energy and Renewable Energy Department of the National Energy Administration, in the first quarter of 2023, 33.66 GW of photovoltaic power was added to the grid nationwide, a year-on-year increase of 154.8%, including 15.53 GW of centralized photovoltaic power generation and 18.13 GW of distributed photovoltaic power generation. As of the end of the first quarter, the installed capacity of photovoltaic power generation in China reached 425 GW, including 249 GW of centralized photovoltaic power generation and 176 GW of distributed photovoltaic power generation. The investment in solar power generation reached 52.2 billion yuan, a year-on-year increase of 177.6%. In the first quarter, the national wind power added 10.40GW of grid connected capacity, including 9.89GW of onshore wind power and 0.51GW of offshore wind power. As of the end of the first quarter, the cumulative installed capacity of wind power in China reached 376GW, a year-on-year increase of 11.8%, including 345GW of onshore wind power and 30.89GW of offshore wind power. Wind power investment completed about 24.9 billion yuan, a year-on-year increase of 15%.

　　From January to April 2023, a total of 73 electrochemical energy storage projects were put into operation, with an installed capacity of 2.523GW/5.037GWh. The installed power increased by 577.1% year-on-year compared to the same period last year (374.4MW). Among them, there are as many as 69 lithium iron phosphate energy storage projects with an installed capacity of 2.52GW/5.019GWh; There are a total of 4 flow battery energy storage projects with an installed capacity of 3.1MW/18.1MWh.

　　The installed capacity of photovoltaic power stations and electrochemical energy storage power stations both increased significantly in the first half of this year. It is expected that, influenced by policy incentives, the photovoltaic storage system will continue to maintain significant growth in the future to meet the requirements of the dual carbon plan.

　　two Market analysis of photovoltaic and energy storage operation and maintenance

　　Along with the rapid development of the photovoltaic and energy storage industries, there are also many tenders for monitoring and operation management projects of existing photovoltaic and wind power plants and energy storage systems. In the first half of 2023, the scale of operation and maintenance tenders for photovoltaic power plant development enterprises was 28.6GW, a year-on-year increase of 204.3%. Among the 28.6GW tender projects mentioned above, a total of 14.9GW have announced their winning bids, as shown in Table 1. The price of photovoltaic outsourcing operation and maintenance varies greatly due to the geographical distribution, capacity, environment, and assessment conditions of photovoltaic power stations. Table 1 shows that the operation and maintenance price is as low as 1.93 yuan/year * kW.
