This solution is applicable to the industrial park with power sales business or the incremental distribution network. Through the precision real-time control of power connected with the external power grid, the self-generating capacity is fully released, and the benefits of power sales is maximized.
• Power grid operation solution
The solution assists the power grid in the industrial park to operate in the mode of “independent operation of virtual enterprise local-area power grid”, and to aggregate the thermal power generating unit, wind power, photovoltaic, controllable load and energy storage device in the power grid into a virtual controllable aggregation through the wide-area distributed system. The solution adopts the technologies and products of our own company, such as whole-grid real-time monitoring, multi-energy complement, harmony between generating unit and grid, load control, grid safety and stability control, etc., so as to complete the operation and scheduling of the power system. The successful implementation of the solution can enhance the stability of the power grid in the industrial park, realize the real-time balance in the park between power side output and large user load, and ensure the users’ power quality in the park. Moreover, it can fully tap the potential of power supply , reduce the on-line power purchase and standby capacity costs, and maximize the benefits of power sales.
• Precision control technology for grid-connected power
Through the modules of emergency steam boiler additional control, emergency load control, tie line over-load shedding, etc., the 10-millisecond high-speed dynamic power balance control technology is adopted to realize the real-time balance between power generation and load, to ensure that the grid-connected power does not break through the limit, to help the enterprises reduce the capacity of grid-connected transformers, to reduce the standby capacity costs, and to facilitate the settlement of power supply services with external power grids.
• Friendly grid-connection technology for new energy power generation
For the multi-energy complementary power grid, the long-term multi-energy complementary operation strategy is designed in view of wind-power, photovoltaic and photothermal periodic fluctuations. In combination of grid-connected power precision control technology, the steam turbine set or other energy storage equipment with steam storage capacity is used to achieve the rapid power balance, to realize the friendly grid connection for new energy generation, and to provide the basis for avoiding the grid companies from restricting wind power and photovoltaic outputs and for reducing the standby capacity costs.
• Power sales & operation solution
It offers the users in the park with professional technical support for the development of three major businesses: power purchase price negotiation, power sales package design, and market service, and provides the overall power sales & operation solution for power sales marketing, customer service, power distribution microgrid, enterprise application, etc.
• Equipment operation & maintenance solution
It integrates the power equipment operation and monitoring information as well as video and auxiliary control information of the substation, so as to realize real-time remote monitoring of power equipment and to make accurate judgment of equipment operating status. It can realize the intelligent operation and maintenance of substation compatible with energy Internet through the mobile interactive remote guidance. It can also assist in building the substation equipment operation & maintenance system with “real-time monitoring, status evaluation, monitoring and early warning, and remote diagnosis” functions for the users.
