Solar Energy and Photovoltaic Industry

The solar energy and photovoltaic industry has evolved from early single power generation applications to a comprehensive energy system covering traditional photovoltaic power station construction, "source-grid-load-storage" integrated systems, and intelligent microgrids. In the traditional photovoltaic field, we undertake electrical system integration for projects such as distributed rooftop power stations, agriculture-photovoltaics complementary systems, and industrial-commercial photovoltaics. We provide a complete automation control solution including photovoltaic array convergence, DC power distribution, inverter grid-connection, AC boosting, and remote monitoring. To address issues in traditional systems such as scattered equipment, opaque operation data, difficult fault location, and low operation and maintenance efficiency, we adopt standardized design and modular control cabinets, combined with PLC and SCADA systems. This enables real-time monitoring of power generation efficiency, inverter group control management, power quality analysis, and remote fault alarms, significantly improving the manageability and operational stability of power stations. On this basis, to tackle the challenges brought by the high proportion of new energy integration, Yongtai Automation Engineering (Shandong) Co., Ltd., as a core partner of Schneider Electric, has further expanded into the fields of "source-grid-load-storage" and microgrids. Relying on Schneider's EcoStruxure™ platform and ETAP power system simulation technology, we provide full-life-cycle solutions from planning to operation and maintenance. Through ETAP, we conduct power flow, short-circuit, protection coordination, and microgrid simulations to optimize system architecture and control strategies. We integrate the EcoStruxure Microgrid Expert system to realize intelligent coordinated dispatching of photovoltaics, energy storage (BMS/PCS), electrical loads, and distribution networks. This supports peak shaving and valley filling, demand control, and seamless switching between off-grid and grid-connected modes, improving energy utilization efficiency and power supply reliability. We can provide customers with one-stop services covering medium and low-voltage power distribution, intelligent meters, data collection, remote monitoring platforms, and customized control logic. This not only meets the needs of stable and efficient operation of traditional photovoltaic projects but also supports the intelligent upgrading of large-scale comprehensive energy projects, helping customers achieve a win-win situation in green and low-carbon transformation and economic benefits.
