Energy management system applied to industrial park

Abstract

The invention provides an energy management system applied to industrial park. The system comprises an energy management center server, a data acquisition unit and an auxiliary communication device. The energy management center server is connected with the data acquisition unit, the data acquisition unit is connected with the auxiliary communication device, and the auxiliary communication device is connected with a field device and a power dispatching mechanism. The field device comprises a power conversion system (PCS), a battery management system (BMS), a photovoltaic grid-connected inverter, a wind-power converter, a gas-driven combined cooling-heating-power supply system, a ground-source heat pump system, branch circuit switchgears, an ammeter, a gas meter, a heat meter and an environmental monitor. According to the energy management system applied to industrial park, energy production and consumption processes are monitored in real time by collecting energy production and consumption information of the industrial park in order to count and analyze the energy production and consumption, and based on energy-saving diagnosis, energy-saving suggests are formed; and the energy source is uniformly dispatched by planning a coordination control strategy, thereby exerting functions of optimizing energy medium balance, improving environmental-protection quality, reducing comprehensive energy consumption of enterprises and reducing energy utilization costs of the enterprises on the industrial park.

Description

technical field [0001] The invention relates to an energy management system. Background technique [0002] With the increasing shortage of energy resources and the increasing demand for energy, the proportion of energy costs in enterprise operating costs is gradually increasing, which also makes enterprise managers and production operators have to reduce enterprise operating costs and improve enterprise comprehensive competition. From the perspective of power, strive to strengthen the energy management of enterprises. Therefore, enterprises urgently need to obtain an integrated solution of energy management and control, and the increasingly mature and widely used energy management system also provides an effective way for enterprise energy information management and continuous improvement of energy efficiency. [0003] The development of energy management can be divided into three stages: the first is extensive management, which only counts the total energy consumption data...

AI Technical Summary

Problems solved by technology

For the energy management system of industrial parks, compared with the existing energy management systems of enterprises or buildings, under the national policy of advocating energy conservation and emission reduction, newly-built industrial parks will introduce more distributed energy systems such as photovoltaic, wind power, and gas trigeneration. Therefore, the energy management of industrial parks is only carried out from the perspective of energy consumption, while ignoring the production units in the park and lacking the control of energy production links. Such an industrial park energy management system is not comprehensive.
