Abstract: Energy management is the key for joint supply micro-grid to use energy effectively. With the present micro-grid management platform, this paper designed a kind of joint supply micro-grid management platform structure frame, adopting layer/step structure, upper lay for central management control, lower layer for disperse control. The software platform adopted an accurate system element equipment model, applying the matured algorithm to solve the optimized model to provide the day before dispatching plan. The real-time dispatching system amended the day before dispatching plan every five minutes to inhibit power wave in the micro-grid and to reduce the impact on the upper dispatching. Diagram, model and data bank integration thought is adopted, to have designed diagram tools, enabling the platform stronger in expansion.
Key words: cold and thermal power joint supply micro-grid; energy management platform; day before dispatch; real-time dispatch;
diagram tool
