【摘要】：為提高電網(wǎng)中的風(fēng)電利用率,一個(gè)可能途徑是通過利用火電機(jī)組的蓄熱能力,使之獲得較快的爬坡速率去響應(yīng)具有波動(dòng)性和間歇性的風(fēng)電出力。本文針對(duì)含風(fēng)電與火電的電力系統(tǒng)經(jīng)濟(jì)調(diào)度問題,提出一個(gè)包含機(jī)組蓄熱利用決策的優(yōu)化模型。含蓄熱的火電機(jī)組與傳統(tǒng)火電機(jī)組不同,其爬坡能力是動(dòng)態(tài)變化且具有記憶性的,因此需要針對(duì)此類機(jī)組建立新的爬坡率約束。文中將上述約束轉(zhuǎn)化為等價(jià)的線性形式,并采用混合整數(shù)規(guī)劃方法求解。仿真算例結(jié)果表明:含蓄熱機(jī)組所提供的額外爬坡能力使系統(tǒng)中的風(fēng)電利用率得到了顯著提高。
[Abstract]:In order to improve the utilization rate of wind power in the power network, one possible way is to make use of the heat storage capacity of the thermal power unit to obtain a faster climbing rate to respond to the fluctuating and intermittent wind power output. In this paper, an optimal model for the economic dispatch of power system with wind power and thermal power is proposed, which includes the decision of heat storage and utilization of generating units. Different from the traditional thermal power units, the thermal thermal units have dynamic slope climbing ability and memory, so it is necessary to establish a new slope climbing rate constraint for this kind of units. In this paper, the above constraints are transformed into equivalent linear forms and solved by mixed integer programming method. The simulation results show that the utilization rate of wind power in the system is greatly improved by the extra climbing ability provided by the implicit heat generating unit.
