Source-Grid-Load-Storage

   Langsung's technical team focuses on integrated "source-grid-load-storage" solutions, utilizing complementary generation, grid-source coordination, grid-load interaction, grid-storage interaction, and source-load interaction to help users achieve economic, efficient, and safe improvements in power system dynamic balancing capabilities, building a new type of power system.

   The "source-grid-load-storage integration" technology maximizes the mobilization and release of the regulation and response capabilities on both the generation side and the load side, promoting precise matching of supply and demand. It enables shared regulation resources in the power system, improves grid safe operation levels, increases the proportion of renewable energy consumption, expands large-scale application of energy storage systems, and promotes coordinated and sustainable development between the energy sector and the ecological environment.

    Multi-Energy Complementarity

    Multi-energy complementary systems operate in two modes: power source terminal and load terminal. Source-side complementary systems utilize wind-solar, wind-solar-hydro, and other hybrid energy types to reduce system output intermittency and uncertainty. Load-side complementary systems use combined heat and power (CHP) and related technologies to meet end-user energy demands for electricity, heating, cooling, and gas, achieving cascaded utilization of energy.

    Based on advanced technologies such as the Energy IoT, IEMS systems, and big data, multi-energy complementary systems feature five major functions: multi-energy-flow SCADA, multi-energy-flow state estimation, multi-energy-flow safety assessment and control, multi-energy-flow optimized scheduling, and multi-energy-flow node energy pricing. These capabilities support the high-quality construction of new power systems, drive clean energy transformation while balancing reliability and economy, and achieve economic and safe decarbonization across the entire society and industry chain.

Microgrid

   Langsung specializes in microgrid technology, using intelligent microgrids to solve power supply challenges in special environments. We build small-scale power generation and distribution systems comprising distributed energy sources, energy storage devices, power conversion equipment, system management software, and protection devices. Leveraging advanced control, communication, computer, and measurement technologies, these systems can operate in parallel with the external grid or in island mode. This facilitates large-scale integration of distributed energy and renewable sources, ensures highly reliable multi-energy supply to loads, and enables the transition from traditional grids to smart grids. The construction of smart microgrids enables bidirectional flow of information and power across all nodes from distributed microgrids and generation equipment clusters to end users, achieving digital, intelligent, and rapid control processes.
