【摘要】：合理地制定企業(yè)微電網(wǎng)自備電廠機(jī)組出力及煤氣消耗計(jì)劃,對降低企業(yè)發(fā)用電成本,減少環(huán)境污染有著非常重要的意義。以企業(yè)微電網(wǎng)發(fā)用電成本最小化為目標(biāo),采用情景樹來描述用電負(fù)荷及煤氣量的不確定性,建立企業(yè)微電網(wǎng)自發(fā)電調(diào)度隨機(jī)優(yōu)化模型。該模型中存在安全約束,采用盒式不確定集合描述該安全約束;為避免盒式集合安全約束過于保守的特性,利用橢圓集合替代盒式集合,通過調(diào)節(jié)風(fēng)險(xiǎn)系數(shù),改變決策的保守特性;給出煤氣柜位狀態(tài)轉(zhuǎn)移圖,將安全約束等價(jià)轉(zhuǎn)化為線性約束進(jìn)行求解。應(yīng)用某大型鋼鐵企業(yè)實(shí)際數(shù)據(jù)進(jìn)行測試,結(jié)果表明:在電網(wǎng)負(fù)荷谷時(shí)段,企業(yè)以電網(wǎng)購電為主;在用電高峰時(shí)段,企業(yè)以自發(fā)電為主;用橢圓集合替代盒式集合,通過調(diào)節(jié)風(fēng)險(xiǎn)系數(shù)能有效避免決策的保守性。
[Abstract]:In order to reduce the cost of electricity consumption and reduce the environmental pollution, it is very important for the enterprise to reduce the cost of electricity generation and reduce the pollution of the environment. The objective is to minimize the cost of electricity consumption in the enterprise microgrid, and the uncertainty of the electric load and coal gas is described by the scenario tree, and the enterprise micro grid is set up to generate electricity. There are security constraints in this model, which describes the security constraint and describes the security constraint by the box uncertain set. In order to avoid the conservative characteristic of the box set security constraints, the ellipse set is used to replace the box set, and the conservative characteristics of the decision are changed by adjusting the risk coefficient; the gas cabinet position state transfer diagram is given, and the security constraint is given. The actual data of a large iron and steel enterprise is tested with the actual data of a large iron and steel enterprise. The results show that in the load valley period of the power grid, the enterprises mainly purchase electricity from the power grid; in the peak period of the electricity consumption, the enterprises are mainly from the power generation; the ellipse set instead of the box set can effectively avoid the conservatism of the decision.
