摘 要： 能量管理是聯(lián)供型微電網(wǎng)能否充分高效利用能源的關(guān)鍵，借鑒現(xiàn)有微電網(wǎng)能量管理平臺，設(shè)計(jì)了一種聯(lián)供型微電網(wǎng)能量管理平臺結(jié)構(gòu)框架，采用分層/分級式的結(jié)構(gòu)，上層集中管理控制，底層分散控制。軟件平臺采用精確的系統(tǒng)元件設(shè)備模型，運(yùn)用成熟的算法，求解優(yōu)化模型提供日前調(diào)度計(jì)劃。實(shí)時(shí)調(diào)度系統(tǒng)每5 min 修正日前調(diào)度計(jì)劃，抑制微電網(wǎng)內(nèi)的功率波動(dòng)，減少對上級調(diào)度的影響。采用圖形模型數(shù)據(jù)庫一體化的思想，設(shè)計(jì)了圖形工具，使平臺的可擴(kuò)展性更強(qiáng)。

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
