Abstract
Description
pが等式制約の数に関連する等式制約hi(x)=0(i=1,...,p)、およびmが不等式制約の数に関連する不等式制約gi(x)≦0(i=1,...,m)下で目的関数f(x)を最小限に抑えるように最適化問題を解くことができる。最適化問題は、
のラグランジアン形態を有することができ、上式で、μiおよびλiはラグランジアン乗数である。この文脈では、「最適化する」「最小限に抑える」「最大限にする」および他の同様の用語は、電力管理問題に対する特定の解を見出すことを指し、それぞれ絶対的な最適、最小、または最大を必要としないことに留意されたい。たとえば、ローカルの最適、最小、または最大は、特定のシステムの効果的な動作にとって異なることがある。他の例として、おおよその最適、最小、または最大は、計算の負担を低減するために、または計算(たとえば、丸め誤差)、通信(たとえば、シグナリング誤差)、制御(たとえば、制御誤差)などに固有の誤差により異なることがある。
式(5)
を最小限に抑えることによって解くことができる。上記の部分問題の総和は、劣勾配法(たとえば、劣勾配最適化プロセス)によって解くことができる凸最適化問題である。劣勾配法は、双対分解問題について上昇方向を見出すことによって最適解に徐々に近づくための反復的な手順である。劣勾配法は、システムコントローラ110において電力管理制御システム104によって実施されてもよい。各シーケンスjにおいて、乗数(λj,μj)を、
λj+1=max(0,λj+αjg(xj)),μj+1=μj+αjh(xj) 式(6)
に従って更新することができ、上式で、αjは、電力管理制御システム104のシーケンスにおいてある期間の値に関連する。たとえば、このシーケンスは、複数の期間(たとえば、時間ステップまたは時間間隔)を含むことができる。
